Features of the Barracuda Message Archiver

Easy Setup and Maintenance

The Barracuda Message Archiver is extremely easy to deploy -- all you need to get started is to install
the Barracuda Message Archiver into your network and configure the method used to retrieve the
messages to be archived. The Web-based interface allows for convenient definition, management and
control of corporate archiving settings and rules from one central location. To minimize ongoing
administration associated with security, automatic delivery of Energize Updates from Barracuda
Central, our advanced technology operations center, keeps the Barracuda Message Archiver up-to­date with the latest protection against viruses and other security threats.

Archiving

The Barracuda Message Archiver can import historical data from many different sources, including
.PST files (Microsoft Outlook’s personal information store). New and existing messages can be
retrieved directly from your mail server using MAPI (Microsoft’s Message Application Protocol
Interface), POP3, or IMAP. Internal company email can be captured along with external emails, even
if journaling is not practical or available at your location, by configuring the Barracuda Message
Archiver to act as an SMTP relay to forward messages to your designated email server. The
Barracuda Message Archiver can also be an SMTP recipient, to work with Bcc journaling (also
known as sidelining), or with the journaling capabilities of the Barracuda Spam Firewall

Intelligent Storage Manager

The Intelligent Storage Manager provides a complete view of used and available storage on the
Barracuda Message Archiver. The built-in storage is on swappable drive trays (hot-swap available
on certain models) to provide added control and email management across an organization’s network,
allowing easy transfer of emails from costly, transaction-based storage required for production email
servers to less expensive storage options. Administrators can also enable storage mirroring for data
redundancy, and add external storage volumes for unlimited storage capacity.

In addition, the Single Instance Storage feature enables the Barracuda Message Archiver to
intelligently remove duplicate emails and attachments that are sent to multiple recipients. Storage
capacity is further maximized by compression of messages before storing it in the file system.

Litigation and Compliance Support

The Barracuda Message Archiver comes with both standard and customizable policies to support
various corporate and legal regulations. In addition to policies on acceptable content, retention
policies are also available to govern the length of time to retain email messages. Alerts can be sent
on detected violations, and easy export of archived messages and access records makes them readily
available for delivery to legal counsel whenever needed.

Introduction 9

Tamper-Resistant Architecture

Users and administrators have only read access to messages that are stored on the Barracuda Message
Archiver, thus making it virtually impossible for someone to intentionally or accidentally corrupt the
archive.

Search and Retrieval

The Search tool located in the Web interface of the Barracuda Message Archiver conducts quick full­text searches based on tags, message content, or message attachments. Users can easily search and
view personal messages in the archive, and forward emails to active mailboxes. Administrators and
Auditors can easily sort through a message archive to compile relevant messages based on keywords,
dates and sender/recipients into an exported file.

Indexing

Using a thorough list of all message components, all messages on the Barracuda Message Archiver
are fully indexed by message content and attachments, with the option to add tags for customized
searches.

Roles

The Barracuda Message Archiver has a role-based permissions system, which allows auditing access
privileges to be granted to individual users. Users can access and create searches only for their own
personal messages in the archive, while auditors have the ability to view, track, and monitor policies
on messages for all users.

Reporting and Statistics

Sophisticated, built-in reports on the Barracuda Message Archiver provides statistics on various
operational and legal aspects. Default reports include the growth of the message archive, policy
violations, and archive traffic.

Energize Updates

Many security technologies are integrated into the Barracuda Message Archiver. In addition to the
virus protection that is standard on all Barracuda Networks products, the Barracuda Message
Archiver also gets the latest in document type and policy definitions via Energize Updates, which are
updated around the clock at Barracuda Central.

Barracuda Message Archiver Configurations

The following are the two most typical deployment methods for the Barracuda Message Archiver:

Journaling Deployment...................................................................... 14

SMTP (or SMTP Relay) Deployment................................................. 15

The deployment mode chosen is usually dependent on the email server configuration that currently
exists at your site, as well as the number of domains that are to be archived.

Table 2.2 shows when each deployment type is recommended.

Table 2.2: Deployment Type Details

If you have... Type of deployment to use

Note

Note

a mail server that is capable of
journaling

a mail server that is NOT capable
of journaling, AND a Barracuda
Spam Firewall

For specific information on the steps required to add new messages to the Barracuda Message
Archiver, see Importing New Messages on page 31. For details on how to add existing messages,
see Importing Historical Data on page 33.

If your email server does not support journaling, AND you do not have a Barracuda Spam Firewall,
contact your Barracuda Networks Sales Representative for further options.

Journaling Deployment

SMTP Relay Deployment

Message Archiving Concepts 13

Journaling Deployment

Networks that utilize email servers capable of journaling can use either a remote journal account to
“pull” messages to be archived, or a special designated SMTP recipient (user account) to “push”
messages to the Barracuda Message Archiver.

Remote Journal Account (Recommended)

In this configuration, the Barracuda Message Archiver is placed off to the side of the email server,
which must have journaling configured to allow the Barracuda Message Archiver to “pull” the
messages directly from the journal account. Emails already on the server prior to journaling being
enabled can still be imported using Microsoft’s Message Application Protocol Interface (MAPI).

Designated SMTP Recipient (Bcc journaling)

If you choose to use a “push” mechanism to send messages to the Barracuda Message Archiver, then
a designated email account, or contact, must exist to be the recipient of all messages that are journaled,
or archived. Journaling must then be configured on the email server to send that user a copy of all
messages that are to be archived, and a forwarding rule created to deliver all messages received by
that user to the Barracuda Message Archiver.

Figure 2.1: Sample Journaling Deployment layout

14 Barracuda Message Archiver Administrator’s Guide

SMTP (or SMTP Relay) Deployment

When journaling on your email server is not available or a practical option, you can use a combination
of the Barracuda Message Archiver and the Barracuda Spam Firewall to capture both external and
internal emails via SMTP. To capture messages sent from external Internet users, you can leverage
the journaling capabilities of the Barracuda Spam Firewall to copy messages to your Barracuda
Message Archiver. To capture messages sent from inside your organization, you can configure
internal email clients to use the Barracuda Message Archiver as an SMTP relay placed in front of your
internal email server.

Figure 2.2: Sample layout for SMTP Relay Deployment

Note

The Barracuda Spam Firewall will only forward messages that it does NOT block to the Barracuda
Message Archiver.

Message Archiving Concepts 15

Other Message Archiving Concepts

Policy Monitoring

Many organizations need to keep track of violations of organizational policy and be alerted when they
occur. Policies can include defining when it is acceptable to send messages containing executable
files or any inappropriate content (usually never); identifying how often messages containing
references to forbidden topics are sent (especially when litigation is expected); and when certain email
recipients can be contacted (excessive personal emails during business hours).

The Barracuda Message Archiver comes with a set of standard policies that are updated regularly via
Energize Updates, and also allows you to easily create your own to fit your specific organization
environment. Alerts can be configured to go out whenever a policy violation is detected, and reports
are available to summarize new policy violations as well as detect any that are found amongst the
messages stored in the archive.

Auditing

Organizations frequently use outside firms to perform an audit of company records. With the
Barracuda Message Archiver, an independent auditor can be provided with complete access to all data
without needing to be added directly into the official directory structure, nor do they need to be given
administrator-level privileges to the entire network.

Specific individuals or accounts can also be given special audit privileges if so desired. Audit
privileges on the Barracuda Message Archiver includes the ability to create and monitor policies, and
flag messages as needed.

Exporting Messages

Messages that are found to be in violation of organizational policy often need to be gathered together
for easy presentation. Once a search has located the messages you want to export, the Barracuda
Message Archiver can export a .zip file containing .eml versions of those messages.

Alias Unification

Each user typically only has one account on the email server, but may have multiple email addresses
(usually variations on their initials and names) that will also reach them. These aliases are resolved
by the email server using protocols such as LDAP, so that messages addressed to an alias are actually
delivered into the appropriate email account.

The Barracuda Message Archiver also will unify the primary account with all of its known aliases, so
that a user will have archive access to all messages received by that user regardless of the "Send To"
address on the message.

Configure Access to the Barracuda

of

Message Archiver

One of the ports listed above is port 25, the default port used for SMTP traffic. Some organizations
have firewall rules that only allow emails to be sent from the IP address of their email server. In these
situations, the corporate firewall will have to be modified to allow emails to be sent from the
Barracuda Message Archiver as well so that system alerts and reports can be emailed.

The Barracuda Message Archiver also should not usually be accepting incoming SMTP requests from
systems outside of your organization’s network. However, if your email server is located in a DMZ,
you may need to configure your corporate firewall to allow incoming traffic over port 25 from your
email server to the Barracuda Message Archiver.

Configure Access to the Barracuda Message Archiver

After specifying the IP address of the Barracuda Message Archiver and opening the necessary ports
on your corporate firewall, configure the Barracuda Message Archiver from the Web administration
interface. Make sure the system being used to access the Web interface is connected to the same
network as the Barracuda Message Archiver, and that the appropriate routing is in place to allow
connection to the Barracuda Message Archiver’s IP address via a Web browser.

This section describes how to customize user access to the Barracuda Message Archiver.

User Accounts .................................................................................... 28

Alias Linking...................................................................................... 28

Group Membership ............................................................................ 29

User Accounts

There are two types of user accounts on the Barracuda Message Archiver:

• Local Accounts: These accounts reside on the Barracuda Message Archiver and are created
from the

• LDAP Accounts: These accounts reside in your LDAP directory. Once LDAP is configured on
the Barracuda Message Archiver, users will be able to log in using their regular network
credentials to view and create flags for messages in their personal archive.

Auditors would typically be a local user account that has been given the role of “auditor”, so that
they have the freedom to monitor all pertinent messages.

Users tab in the administration interface.

To create a local user account:

1. Go to the Users > User Add/Update page.

2. In the User Account(s) box, enter the username for this new account. To create more than one

account in one step, enter each username on a line by itself. Usernames are case-sensitive.

3. Click Save Changes to create the specified user accounts.

To assign auditor privileges to an account:

1. Go to the Users > Account View page.

2. The Profile column for lists the current role assigned to a user. Click on the role shown for the

user whose privileges you want to change to bring up another window from which you can
adjust the role as desired for the user.

3. Click Save Changes to change the role for that user. This account is now displayed on the

Account View page with its new role.

Alias Linking

LDAP users often have one primary email address that is their user account name along with several
aliases for convenience. For example, [e-mail] might also receive messages as
[e-mail], [e-mail], and [e-mail]. For organizations
that use LDAP, messages sent to any alias are also accessible from the primary user account on the
Barracuda Message Archiver.

You can also create a local user account with access to archived emails for a select list of users. For
example, you would like a single user account to be able to see emails for [e-mail],
[e-mail], and [e-mail], in addition to [e-mail].
To do so, create a local account on the Barracuda Message Archiver (for example, “local_boss”), and
list as aliases the email addresses to which that account should have access.

28 Barracuda Message Archiver Administrator’s Guide

To list aliases for an account:

1. Go to the Users > Account View page.

2. Click the entry in the Profile column for the primary user account. Doing so will bring up

another window in which you can specify the email aliases for the user.

3. Click Save Changes to save the list of aliases for that user. This account is now be displayed on

the Account View page with its new role.

Group Membership

Archived messages that are sent to a mailing group will be visible in the personal message archive for
every member of that group. For example, if [e-mail], [e-mail], and
[e-mail] are all members of [e-mail], then any message that is sent to
[e-mail] will be available in the archives of all three users.

Configuring the Barracuda Message Archiver 29

Configuring Storage

The Barracuda Message Archiver has swappable internal disk storage that is sized according to
model, as well as the ability to use external drives for unlimited storage.

Hot swappable disks are offered on the Barracuda Message Archiver 650.

Note

Maintenance for any external storage that is added to the Barracuda Message Archiver can and
should be performed as you would for any other data storage device.

Intelligent Storage Manager

The Advanced > Intelligent Storage Manager page contains the controls needed to manage both the
internal and external storage volumes used.

Mirroring

Enabling mirroring of storage data will provide data redundancy for added protection against any
possible corruption of the actual hardware, but will reduce the overall capacity of your drives.

Adding Storage

The table below outlines the internal storage capacity provided by the Barracuda Message Archiver.

Table 4.1: Specifications for Built-In Storage

Model Storage Capacity RAID / Physical Size

350 0.5 Terabytes RAID-1 / 1.0 TB

450 1.0 Terabytes RAID-1 / 2.0 TB

650 2.0 Terabytes RAID-5 / 3.0 TB

The Barracuda Message Archiver can be configured to use external storage volumes for virtually
unlimited archiving capacity. Any external volume that supports the SMB/CIFS filesharing protocols
can be used as external storage.

30 Barracuda Message Archiver Administrator’s Guide

Importing New Messages

There are several ways in which the Barracuda Message Archiver can receive new messages for
archiving, depending on your network configuration. See the section on Barracuda Message
Archiver Configurations on page 13 to determine the best deployment scenario for your corporation.

For specifics on how to set up in your environment, please reference the following sections:.

Journaling Email Server .................................................................... 31

Barracuda Spam Firewall.................................................................. 32

Journaling Email Server

This is the recommended method of sending messages to the Barracuda Message Archiver.

If your email server is capable of journaling, make sure that it is set up and enabled per the directions
for your particular email server. The Barracuda Message Archiver has been tested and verified to
work with many different types of journaling email servers, including (but not limited to):

• Microsoft Exchange

• Novell Groupwise (6.5 and higher only)

• IBM/Lotus Domino

•IPSwitch Imail

To set up a Remote Journal Account deployment:

1. Configure your email server to journal messages, per the directions for your particular email

server.

2. From the Basic > Remote Journal Accounts page on the Barracuda Message Archiver, supply

the following information for each email server from which you wish to archive:

2a. The name of your email server
2b. The protocol (IMAP, POP) used to connect to your email server
2c. The name of the journaling account, or journaling email address, on your email server
2d. The password (if required) for the journaling account
2e. Whether or not messages are to be removed from your email server once it has been

added to the Barracuda Message Archiver

3. Click Save Changes to preserve your settings.

4. The Barracuda Message Archiver will immediately begin pulling messages from the designated

journaling accounts.

To set up a Designated SMTP Recipient:

1. Identify an email address that is to receive all journaled messages. This can be an account

created on your email server, or it can be an email address in the following format:
journalname@fully_qualified_domain_name_of_Barracuda_Message_Archiver
or username@[ip_address_of_Barracuda_Message_Archiver]

Examples: [e-mail]
archive@[192.168.2.24]

2. Configure journaling on your email server so that all journaled messages are actually delivered

to the designated email address.

Configuring the Barracuda Message Archiver 31

3. If you created an account on your email server, then you will also need to create a forwarding

rule on your email server to deliver all messages received by that user to the Barracuda Message
Archiver.

Barracuda Spam Firewall

If you have a Barracuda Spam Firewall and your email server has journaling capabilities, then it is
recommended that you set up Remote Journal Accounts as outlined above. However, if your email
server is not able to journal messages, you can configure your Barracuda Message Archiver to act as
an SMTP proxy to your email server and activate the journaling feature that is available on Barracuda
Spam Firewall (firmware versions 3.5 and higher) to submit messages to the Barracuda Message
Archiver.

Note

The Barracuda Message Archiver MUST be configured to be the SMTP relay even for all internal
email traffic, since messages that bypass the Barracuda Spam Firewall will not be available for
journaling. Please refer to Figure 2.2: Sample layout for SMTP Relay Deployment on page 15 for
an illustration of the required traffic flow.

To set up journaling on your Barracuda Spam Firewall:

1. On your Barracuda Spam Firewall (firmware version 3.5 and higher), go to Advanced >

Journaling

2.

In the Destination E-mail Address field, enter an SMTP recipient in the form:
username@[ip_address_of_Barracuda_Message_Archiver]

Example: archive@[192.168.2.24]

3. In the Journal Message Bounce Address field, enter the email address that is to receive all

bounce notifications from the Barracuda Message Archiver.

4. Click Save Changes.

5. The Barracuda Spam Firewall will now begin to send a copy of every delivered message to the

Barracuda Message Archiver. You will then need to configure the

Advanced > SMTP Proxy

setting on the Barracuda Message Archiver to forward messages to your email server.

32 Barracuda Message Archiver Administrator’s Guide

Importing Historical Data

Auditing 35

Auditing Basics

The Barracuda Message Archiver allows you to implement and monitor policies regarding your email
traffic, and identify both newly arrived and existing messages that meet any criteria you wish to
specify. Local auditor accounts can be created on the Barracuda Message Archiver, to negate the need
for creating temporary users with special access in your corporate directory or email server. Available
auditing features include:

• creating searches on virtually every aspect of a message

• exporting and forwarding copies of archived messages

• receiving alerts when messages matching particular criteria are detected

• tagging specific emails, for easier re-identification

Creating Searches

The Basic > Search page of Barracuda Message Archiver displays a list of the messages that are
archived. Searches can be made on virtually every aspect of a message, including:

• message body content

• recipients and senders

• attachment type and content

•date

Please refer to the online help for this feature on the
of available search parameters.

Once you have designed a search that identifies the desired messages, you can save and name the
search for use in a policy alert. A list of all saved searches and their definitions are listed on the

Policy/Alerts > Saved Search Definitions page.

Exporting and Forwarding Messages

Copies of messages can be easily exported from the Basic > Search page. To export one or more
messages, select the desired items from the message list and click the Export Selected button. To
export all search results, click the Export All button.

To forward one or more messages, select the desired items from the message list, enter the email
addresses to which you wish to forward the messages, and click the Forward To: button. To forward
all search results, enter the email addresses to which you wish to forward the messages and click the
Forward All button.

Creating Policy Alerts

The Barracuda Message Archiver comes with 3 default policy definitions that are updated regularly
by Energize Updates to meet the latest standards:

Basic > Search page for the most up-to-date list

• Personal Email

• Personal Info

• Foul Language

36 Barracuda Message Archiver Administrator’s Guide

Administrators and auditors can choose to add themselves to the alerts list for these standard policies,
and also choose to be alerted whenever messages meeting their own particular criteria (as defined and
saved in a search) are entered into the archive.

The Policy/Alerts > Policy Alerts page allows you to specify the email addresses that are to receive an
email notification whenever messages matching the parameters in a saved search are detected.

Tagging Messages

The Basic > Search page also allows you to tag any message, for easy retrieval. Select the message(s)
you wish to tag, enter the text label, or tag, you wish to use, and click on the Tag: button. These tags
can then be used as a search criteria, to allow you to easily re-identify any message in the archive.

information on a replacement Barracuda Message Archiver or in the event your current system data
becomes corrupt.

If you are restoring a backup file on a new Barracuda Message Archiver that is not configured, you
need to assign your new system an IP address and DNS information on the
page.

Basic > IP Configuration

Note the following about the backup file:

• Do not edit backup files. Any configuration changes you want to make need to be done through
the Web interface. The configuration backup file contains a checksum that prevents the file from
being uploaded to the system if any changes are made.

• You can safely view a backup file in Windows WordPad or Microsoft Word. You should avoid
viewing backup files in Windows Notepad because the file can become corrupted if you save the
file from this application.

• The following information is not included in the backup file:

• System password

• System IP information

•DNS information

Updating the Firmware of Your Barracuda Message Archiver

The Advanced > Firmware Update page allows you to manually update the firmware version of the
system or revert to a previous version. The only time you should revert back to an old firmware
version is if you recently downloaded a new version that is causing unexpected problems. In this case,
call Barracuda Networks Technical Support before reverting back to a previous firmware version.

If you have the latest firmware version already installed, the

Download Now button will be disabled.

Using the Built-in Troubleshooting Tools

The Advanced > Troubleshooting page provides various tools that help troubleshoot network
connectivity issues that may be impacting the performance of your Barracuda Message Archiver.

For example, you can test your Barracuda system’s connection to Barracuda Central to make sure it
can successfully download the latest Energize Update definitions. You can also ping other devices
from the Barracuda Message Archiver, perform a traceroute from the Barracuda Message Archiver to
any another system, and other tasks.

Rebooting the System in Recovery Mode

If your Barracuda Message Archiver experiences a serious issue that impacts its core functionality,
you can use diagnostic and recovery tools that are available at the reboot menu to return your system
to an operational state.

Before you use the diagnostic and recovery tools, do the following:

• Use the built-in troubleshooting tools on the

Advanced > Troubleshooting page to help diagnose

the problem.

• Perform a system restore from the last known good backup file.

• Contact Barracuda Networks Technical Support for additional troubleshooting tips.

As a last resort, you can reboot your Barracuda Message Archiver and run a memory test or perform
a complete system recovery, as described in this section.

To perform a system recovery or hardware test:

1. Connect a monitor and keyboard directly to your Barracuda Message Archiver.

2. Reboot the system by doing one of the following:

•Click

Restart on the Basic > Administration page.

• Press the Power button on the front panel to turn off the system, and then press the Power
button again to turn back on the system.

The Barracuda splash screen displays with the following three boot options:

Barracuda
Recovery
Hardware_Test

3. Use your keyboard to select the desired boot option, and press Enter.

You must select the boot option within three seconds of the splash screen appearing. If you do
not select an option within three seconds, the Barracuda Message Archiver defaults to starting
up in the normal mode (first option).

For a description of each boot option, refer to Reboot Options on page 47.

Note

To stop a hardware test, reboot your Barracuda Message Archiver by pressing Ctrl-Alt-Del.

Reboot Options Description

Barracuda Starts the Barracuda Message Archiver in the normal (default) mode.

This option is automatically selected if no other option is specified
within the first three (3) seconds of the splash screen appearing.

Recovery Displays the Recovery Console where you can select the following

options:

• Perform filesystem repair—Repairs the file system on the
Barracuda Message Archiver.

• Perform full system re-image—Restores the factory settings on
your Barracuda Message Archiver and clears out all configuration
information.

• Enable remote administration—Initiates a connection to Barracuda
Central that allows Barracuda Networks Technical Support to access
the system. Another method for enabling this toubleshooting
connection is to click Establish Connection to Barracuda Central
on the Advanced-->Troubleshooting page.

• Run diagnostic memory test—Runs a diagnostic memory test from
the operating system. If problems are reported when running this
option, we recommend running the Hardware_Test option next.

Open Source Licensing

Barracuda products may include programs that are covered by the GNU General Public License
(GPL) or other "open source" license agreements. The GNU license is re-printed below for you
reference. These programs are copyrighted by their authors or other parties, and the authors and
copyright holders disclaim any warranty for such programs. Other programs are copyright by
Barracuda Networks.

GNU GENERAL PUBLIC LICENSE, (GPL) Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing
it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By
contrast, the GNU General Public

License is intended to guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to using it. (Some other Free
Software Foundation software is covered by the GNU Library General Public License instead.) You can
apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses
are designed to make sure that you have the freedom to distribute copies of free software (and charge
for this service if you wish), that you receive source code or can get it if you want it, that you can
change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or
to ask you to surrender the rights. These restrictions translate to certain responsibilities for you
if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whethergratis or for a fee, you must give the
recipients all the rights that you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that
there is no warranty for this free software. If the software is modified by someone else and passed
on, we want its recipients to know that what they have is not the original, so that any problems
introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger
that redistributors of a free program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any patent must be licensed for
everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the copyright
holder saying it may be distributed under the terms of this General Public License. The "Program",
below, refers to any such program or work, and a "work based on the Program" means either the Program
or any derivative work under copyright law: that is to say, a work containing the Program or a portion
of it, either verbatim or with modifications and/or translated into another language. (Hereinafter,
translation is included without limitation in the term "modification".) Each licensee is addressed
as "you".

Activities other than copying, distribution and modification are not covered by this License; they are
outside its scope. The act of running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the Program (independent of having been
made by running the Program). Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any
medium, provided that you conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License
and to the absence of any warranty; and give any other recipients of the Program a copy of this
License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based
on the Program, and copy and distribute such modifications or work under the terms of Section 1 above,
provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed the files

and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or

is derived from the Program or any part thereof, to be licensed as a whole at no charge to all
third parties under the terms of this License.

57

c) If the modified program normally reads commands interactively when run, you must cause it,

when started running for such interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice that there is no warranty (or
else, saying that you provide a warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this License. (Exception: if the Program
itself is interactive but does not normally print such an announcement, your work based on the
Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are
not derived from the Program, and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those sections when you distribute them
as separate works. But when you distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote
it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written
entirely by you; rather, the intent is to exercise the right to control the distribution of derivative
or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a
work based on the Program) on a volume of a storage or distribution medium does not bring the other
work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or
executable form under the terms of Sections 1 and 2 above provided that you also do one of the
following:

a) Accompany it with the complete corresponding machine-readable source code, which must be

distributed under the terms of Sections 1 and 2 above on a medium customarily used for software
interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for

a charge no more than your cost of physically performing source distribution, a complete machine­readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and
2 above on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute corresponding

source code. (This alternative is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an offer, in accord with Subsection
b above.)

The source code for a work means the preferred form of the work for making modifications to it. For
an executable work, complete source code means all the source code for all modules it contains, plus
any associated interface definition files, plus the scripts used to control compilation and
installation of the executable. However, as a special exception, the source code distributed need not
include anything that is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on which the executable runs, unless
that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not compelled to copy the source along
with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under
this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void,
and will automatically terminate your rights under this License. However, parties who have received
copies, or rights, from you under this License will not have their licenses terminated so long as
such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Program or its derivative works. These actions
are prohibited by law if you do not accept this License. Therefore, by modifying or distributing
the Program (or any work based on the Program), you indicate your acceptance of this License to do
so, and all its terms and conditions for copying, distributing or modifying the Program or works
based on it.

6. Each time you redistribute the Program (or any work based on the Program), the recipient

automatically receives a license from the original licensor to copy, distribute or modify the Program
subject to these terms and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing compliance by third
parties to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or for any other

reason (not limited to patent issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this License, they do not excuse you from
the conditions of this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a consequence you may
not distribute the Program at all. For example, if a patent license would not permit royalty-free
redistribution of the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain entirely from
distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software distributed through that
system in reliance on consistent application of that system; it is up to the author/donor to decide

58 Barracuda Message Archiver Administrator’s Guide

if he or she is willing to distribute software through any other system and a licensee cannot impose
that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of
this License.

8. If the distribution and/or use of the Program is restricted in certain countries either by patents

or by copyrighted interfaces, the original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such case, this License
incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the General Public License
from time to time. Such new versions will be similar in spirit to the present version, but may differ
in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies a version number of
this License which applies to it and "any later version", you have the option of following the terms
and conditions either of that version or of any later version published by the Free Software Foundation.
If the Program does not specify a version number of this License, you may choose any version ever
published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs whose distribution

conditions are different, write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT

PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER,

OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO
YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF
THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion
of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

one line to give the program's name and an idea of what it does.

Copyright (C) yyyy name of author

This program is free software; you can redistribute it and/or modify it under the terms of the GNU
General Public License as published by the Free Software Foundation; either version 2 of the License,
or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even
the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General
Public License for more details.

You should have received a copy of the GNU General Public License along with this program; if not,
write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO
WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use
may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.
Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes
passes at compilers) written by James Hacker.

signature of Ty Coon, 1 April 1989
Ty Coon, President of Vice

This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public
License instead of this License.

result of this License or out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other
commercial damages or losses), even if such Contributor has been advised of the possibility of such
damages.

9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works

thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this License. However, in accepting such
obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any
other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for
any liability incurred by, or claims asserted against, such Contributor by reason of your accepting
