About the PGP Universal Server Installation Guide

The PGP Universal Server Installation Guide provides important PGP™ Universal Server concepts and presents a high-level overview of the tasks required to install, set up, and use PGP Universal Server. This guide provides information about how your PGP Universal Server processes email, which helps you integrate your PGP Universal Servers into your network. There is also information on using Microsoft Server and Lotus® Domino® Server with PGP Universal Satellite.

What is PGP Universal Server?

PGP Universal Server is a console that manages the applications that provide email, disk, and network file encryption. PGP Universal Server with PGP Universal Gateway Email provides secure messaging by transparently protecting your enterprise messages with little or no user interaction. The PGP Universal Server replaces PGP Keyserver with a built-in keyserver, and PGP Admin with PGP Desktop configuration and deployment capabilities.

PGP Universal Server also does the following:  Automatically creates and maintains a Self-Managing Security Architecture

(SMSA) by monitoring authenticated users and their email traffic.

 Allows you to send protected messages to addresses that are not part of the SMSA.  Automatically encrypts, decrypts, signs, and verifies messages.  Provides strong security through policies you control.

PGP Universal Satellite, a client-side feature of PGP Universal Server, does the following:

 Extends security for email messages to the computer of the email user.  Allows external users to become part of the SMSA.  If allowed by an administrator, gives end users the option to create and manage

their keys on their computers.

PGP Desktop, a client product, is created and managed through PGP Universal Server policy and does the following:

 Creates PGP keypairs.  Manages user keypairs.  Stores the public keys of others.  Encrypts user email and instant messaging (IM).  Encrypts entire, or partial, hard drives.  Enables secure file sharing with others over a network.

Add the PGP Universal Server to Your Network

This chapter provides information about how your PGP Universal Server processes email, which can help you decide how to integrate your PGP Universal Servers into your network. It also includes information about using Microsoft Exchange Server and Lotus Domino Server with PGP Universal Satellite.

Server Placement

In your network, a PGP Universal Server can be placed in one of the following locations:

 Internal placement, where the PGP Universal Server is located between your

 Gateway placement, where the PGP Universal Server is located between your

email users and their local mail server.

external facing mail server and the Internet.

Gateway Placement

Caution: Unless it is a transparent proxy, do not place the PGP Universal Server

behind a proxy server to automatically receive licensing and update information.

In a gateway placement, your PGP Universal Server sits between your mail server and the Internet in the logical flow of data.

External email user Logical flow of data Example Corp. internal network Example Corp. email users

8 Add the PGP Universal Server to Your Network

Server Placement

Example Corp. email server

Note: The physical location of the PGP Universal Server and the mail server are not

important. From a mail relay perspective, it is more important that the PGP Universal Server is between the mail server and the Internet. Both can be on the internal network or in the DMZ.

In this placement, remember the following:  When you use SMTP, email messages are secured before they are sent to the

Internet and decrypted/verified when received from the Internet.  Email users on your internal network should not have direct access to a PGP

Universal Server in the gateway placement.

Based on your configuration, PGP Universal Server attempts to enforce this lack of

access automatically .  If you plan to use the signing features in PGP Universal Server, configure the mail

server to verify the From addresses.  Unless PGP Universal Satellite is used, messages are stored unsecured on the mail

server.  For PGP Universal Server to create the SMSA, you must configure your mail server

correctly.

Internal Placement

In this placement, your PGP Universal Server sits between your email users and their email server.

Mail Relay 9

Mail Relay

Example Corp. email users

Note: The physical location of the PGP Universal Server and the mail server are not

important. From a mail relay perspective, it is more important that the PGP Universal Server is between the email users and the mail server; both can be on the internal network or in the DMZ. From a performance perspective, you should place users and the mail server next to each other on the same network.

In this PGP Universal Server placement, when messages are sent to the mail server using SMTP, they are secured based on the applicable policies. Using POP or IMAP, messages are decrypted and verified when they are retrieved from the mail server. If PGP Universal Satellite has not been deployed globally to your internal users, messages are stored secured on the mail server and are only transmitted unencrypted between the internal user and the PGP Universal Server. If your mail server is configured for SSL/TLS communications with the email client, messages are sent through that encrypted channel and remain encrypted through the entire path. For PGP Universal Server to create the SMSA, email clients must have SMTP authentication switched on when they communicate with a PGP Universal Server.

After processing outgoing email, PGP Universal Server can forward the email to a central mail gateway, which acts as a mail relay. Sites that use explicit mail routing can use mail relay to forward outgoing email to a mail relay that performs explicit routing.

You cannot configure the mail relay during the initial configuration in the Setup Assistant. Instead, you have to configure the server for gateway placement and configure the mail relay in the administrative interface. For more information on configuring the relay on the Outbound or Unified SMTP proxy, see Creating New or Editing Existing Proxies in the PGP Universal Server Administrator's Guide.

Microsoft Exchange Server

Messaging Application Programming Interface (MAPI) support is available for Microsoft Exchange Server environments by using PGP Desktop or PGP Universal Satellite for Windows. MAPI support is not available in PGP Universal Satellite for Mac OS X because there are no MAPI email clients for Mac OS X.

For more information about using MAPI, see Exchange with PGP Client Software (on

46) and MAPI Support in the PGP Universal Server Administrator's Guide.

page

Lotus Domino Server

Lotus Domino Servers and the Lotus Notes email client (versions 7.0.3 and later) are supported in PGP Desktop and PGP Universal Satellite for Windows

10 Add the PGP Universal Server to Your Network

Installation Overview

For more information about using the Lotus Notes email client, see Lotus Domino Server with PGP Client Software (on page 46) and Lotus Notes Support in the PGP Universal Server Administrator's Guide.

Installation Overview

This a broad overview of the process to plan, set up, and maintain your PGP Universal Server environment.

Steps 1 and 4 are described in this guide, but the other steps are described in the PGP Universal Server Administrator's Guide. This process applies a new, stand-alone installation of PGP Universal Server. If you plan to install a cluster, you must install and configure one PGP Universal Server following this process. Additional cluster members receive most of their configuration settings from the initial PGP Universal Server through data replication.

1 Plan where in your network you want to locate your PGP Universal Server(s).

Where you put PGP Universal Servers in your network, how many PGP Universal

Servers you have in your network, and other factors impact how you add the PGP

Universal Servers to your existing network. To help you plan, you should create a

diagram of your network that includes the network components and your email

flows. This diagram should also include details about the impact on your network

of adding a PGP Universal Server. For more information on how to add PGP

Universal Servers to your existing network, see Adding the PGP Universal Server to

Your Network (see " 2 Perform the necessary DNS changes.

This involves tasks such as the following:

 Adding IP addresses for your PGP Universal Servers and an alias to your

keyserver.

 Updating the MX record if necessary.  Adding keys.<domain>, hostnames of potential Secondary servers for a

cluster, and so on.

Properly configured DNS settings, such as root servers and appropriate reverse

lookup records, are required to support PGP Universal Server. You host and

pointer records must be correct. IP addresses must be resolvable to hostnames,

and hostnames must be resolvable to IP addresses. 3 Prepare a hardware token Ignition Key.

To add a hardware token Ignition Key during set up, you must install the drivers

and configure the token before you set up the PGP Universal Server. For

information on preparing a hardware token Ignition Key, see Protecting PGP

Universal Server with Ignition Keys in the PGP Universal Server Administrator's

Guide .

Add the PGP Universal Server to Your Network" on page 7).

Note: In a cluster, the Ignition Key that is configured on the first PGP Universal

Server in the cluster also applies to subsequent members of the cluster. 4 Install and configure PGP Universal Server.

Add the PGP Universal Server to Your Network

Installation Overview

The Setup Assistant runs automatically when you access the PGP Universal Server

administrative interface for the first time. You can set or confirm a number of

basic settings, such as your network settings, administrator password, server

placement option, mail server address, and so on. For more information on this

process, see Setting Up the PGP Universal Server (see "

Universal Server" on page

27).

About Setting Up PGP

Note:To configure multiple servers as a cluster, you must first configure one

server and add the additional servers as cluster members. You can do this

through the Setup Assistant when you install a server that will join an existing

cluster or through the PGP Universal Server administrative interface. For more

information, see Cluster Member Configuration (see "

Member" on page

31).

Configuring a Cluster

5 License your server.

You must license PGP Universal Server to take it out of Learn Mode or install

updates. After it is licensed, you should check for and install product updates. If

you want the PGP Universal Server to provide mail proxy services, you must have

a PGP Universal Server license with the mailstream feature enabled and select the

Enable Mail Proxies checkbox on the System Settings page. For more

information, see Licensing Your Software in the PGP Universal Server

Administrator's Guide.

6 Import the PGP key you want to use as your Organization Key with PGP

Universal Server and back it up.

Your Organization Key is used to sign all user keys the PGP Universal Server

creates and encrypt PGP Universal Server backups. This key represents the

identity of your organization and is the root of the Web-of-Trust for your users.

If your organization uses PGP Desktop and has an Corporate Key or Organization

Key that you want to use with PGP Universal Server, you should import it after

configuring your server. If your organization does not have a key to use as your

Organization Key, you can use the Organization Key that the Setup Assistant

automatically created with default values. For more information, see Managing

Organization Keys in the PGP Universal Server Administrator's Guide.

Note: Regardless of which key you use as your Organization Key, you must back

up the key.

Since PGP Universal Server’s built-in back-up feature always encrypts backups to

this key, you must provide a copy of your Organization Key to restore your data.

For more information, see Organization Certificate in the PGP Universal Server

Administrator's Guide.

7 Add the PGP Additional Decryption Key (ADK) that you want to use with PGP

Universal Server.

An Additional Decryption Key (ADK) allows you to recover an email message if the

recipient is unable or unwilling to do so; every message that is encrypted to the

ADK can be opened by the holder(s) of the ADK. You cannot create an ADK with

the PGP Universal Server, but if you have an existing PGP ADK generated by PGP

Desktop, you can add it to your PGP Universal Server and use it. For more

information, see the PGP Desktop User’s Guide and Additional Decryption Key

(ADK) in the PGP Universal Server Administrator's Guide. 8 Create a SSL/TLS certificate or obtain a valid SSL/TLS certificate.

12 Add the PGP Universal Server to Your Network

Installation Overview

The Setup Assistant automatically creates a self-signed certificate to be used with

SSL/TLS traffic. Because this certificate is self-signed, it might not be trusted by

email or Web browser clients. Symantec Corporation recommends that you obtain

a valid SSL/TLS certificate for each of your PGP Universal Servers from a

reputable Certificate Authority. This is especially important for PGP Universal

Servers that are publicly accessed. Older Web browsers might reject self-signed

certificates or not know how to handle them when they encounter them through

PGP Universal Web Messenger or Smart Trailer. For more information, see

Working with Certificates in the PGP Universal Server Administrator's Guide.

9 Configure the Directory Synchronization feature if you want to synchronize an

LDAP directory with your PGP Universal Server.

If you have an existing LDAP server, Directory Synchronization provides more

control over who is included in your SMSA. By default, user enrollment is set to

Email enrollment. If you decide to use LDAP directory enrollment, this enrollment

type assumes that you have an LDAP directory configured. You can change the

client enrollment setting for Directory Synchronization in the Directory

Synchronization Settings page.

Note: For LDAP user enrollment to work, you must have a configured LDAP

directory and have enabled Directory Synchronization.

For more information, see Using Directory Synchronization to Manage Users in

the PGP Universal Server Administrator's Guide. 10 Configure PGP Desktop client features.

By default, the PGP Desktop client basic license is installed with the PGP Universal

Server, so you do not have to add the client license separately. However, optional

features, such as messaging, PGP Whole Disk Encryption, and PGP NetShare, are

disabled by default. If you purchased a license for those features, you must edit

your client policy settings to enable them. For more information about consumer

policy settings, see Establishing PGP Desktop Settings for Your PGP Desktop

Clients in the PGP Universal Server Administrator's Guide. 11 Add trusted keys, configure consumer policy, and establish mail policy.

These settings are important to operate PGP Universal Server securely.

 For more information on adding trusted keys from outside the SMSA, see

Managing Trusted Keys and Certificates in the PGP Universal Server Administrator's Guide.

 For more information about consumer policy settings, see Administering

Consumer Policy.

 For information on setting up mail policy, see Setting Mail Policy.

When setting consumer policies, PGP Universal Server provides Out of Mail

Stream (OOMS) support. This option specifies how the email is transmitted from

the client to the server if PGP Desktop cannot find a key for the recipient and,

therefore, cannot encrypt the message. OOMS is disabled by default, so sensitive

messages that cannot be encrypted locally are sent unencrypted to PGP Universal

Server "in the mail stream" like typical emails. Mail or Network administrators can

read these messages by accessing the mail server's storage or monitoring network

traffic. However, archiving solutions, outbound anti-virus filters, or other systems

that monitor or proxy mail traffic will process these messages normally.

Add the PGP Universal Server to Your Network

Installation Overview

You can enable OOMS, which means that sensitive messages that cannot be

encrypted locally are sent to PGP Universal Server "out of the mail stream." PGP

Desktop creates a separate, encrypted network connection to the PGP Universal

Server to transmit the message. However, archiving solutions, outbound anti-virus

filters, or other systems that monitor or proxy mail traffic will not see these

messages.

When you configure PGP Universal Server, you should determine the appropriate

settings for your requirements. This option can be set separately for each policy

group, and is set in the Consumer Policy page. For more details on the effects of

enabling or disabling OOMS, see Out of Mail Stream Support in the PGP Universal

Server Administrator's Guide. 12 Install and configure additional cluster server members.

You can do this through the Setup Assistant when you install a server that will

join an existing cluster or through the PGP Universal Server administrative

interface. You must configure one server before you can add and configure

additional servers as cluster members. For more information, see Clustering your

PGP Universal Servers in the PGP Universal Server Administrator's Guide.. 13 Reconfigure the settings of your email clients and servers, if necessary.

Depending on how you add the PGP Universal Server to your network, some

setting changes might be necessary. For example, if you are using a PGP Universal

Server that is placed internally, the email clients must have SMTP authentication

switched on. For PGP Universal Servers that are placed externally, you must

configure your mail server to relay SMTP traffic to the PGP Universal Server. 14 Enable SNMP Polling and Traps.

You can configure PGP Universal Server to allow network management

applications to monitor system information for the device on which PGP Universal

Server is installed and send the information to an external destination. For more

information see Configuring SNMP Monitoring in the PGP Universal Server

Administrator's Guide.

15 Distribute PGP Universal Satellite and/or PGP Desktop to your internal users, if

appropriate.

To provide seamless, end-to-end message security without training your users,

you can use PGP Universal Satellite. Exchange/MAPI and Lotus Notes

environments also require PGP Universal Satellite. PGP Desktop provides more

features and user control than PGP Universal Satellite does. For more information,

see PGP Universal Satellite and Configuring PGP Desktop Installations in the PGP

Universal Server Administrator's Guide. 16 Analyze the data from Learn Mode.

In Learn Mode, your PGP Universal Server does the following:

 Sends messages through mail policy without taking action on the messages.  Decrypts and verifies incoming messages when possible.  Dynamically creates a SMSA.

You can see what the PGP Universal Server would have done without Learn Mode

by monitoring the system logs. Learn Mode helps you become familiar with how

the PGP Universal Server operates and allows you to see the effects of your policy

settings before the PGP Universal Server goes live on your network. You can tune

settings in Learn Mode, so that the PGP Universal Server is operating properly

when you go live. For more information, see Operating in Learn Mode in the PGP

Universal Server Administrator's Guide.

14 Add the PGP Universal Server to Your Network

Installation Overview

17 Adjust policies as necessary.

You should review your current policies and make the necessary changes. 18 Back up all PGP Universal Servers before taking them out of Learn Mode.

This gives you a baseline backup if you need to return to a clean installation. For

more information, see Backing Up and Restoring System and User Data in the PGP

Universal Server Administrator's Guide. 19 Take your PGP Universal Servers out of Learn Mode.

Now email messages are encrypted, signed, and decrypted/verified, based on the

relevant policy rules.

20 Monitor the system logs to ensure that your PGP Universal Server environment

is operating as expected.

About Naming your PGP Universal Server

This chapter describes how and why to name your PGP Universal Server using the

How to Name Your PGP Universal Server

keys.<domain> convention.

Unless a valid public key is found locally, PGP Universal Servers automatically look for valid public keys for email recipients by attempting to contact a keyserver at a special hostname, keys.<domain>, where <domain> is the recipient's email domain.

For example, an internal user at example.com sends an email to

susanjones@widgetcorp.com. If no valid public key for Susan is found on the Example

PGP Universal Server, it automatically looks for a valid public key for Susan at keys.widgetcorp.com, even if there is no domain policy for widgetcorp.com on Example’s PGP Universal Server. Keys are found locally if they are cached, or if Susan was an external user who explicitly supplied her key through PGP Universal Web Messenger. If the Widgetcorp PGP Universal Server is named using the keys.<domain> convention, the Example Corp. PGP Universal Server can find a valid public key for

susan@widgetcorp.com at keys.widgetcorp.com.

Caution: Symantec Corporation strongly recommends you name your PGP Universal

Server according to this convention, because it allows other PGP Universal Servers to easily find valid public keys for email recipients in your domain. You must also use this convention to name your externally visible PGP Universal Server.

If your organization uses email addresses, such as mingp@example.com and

mingp@corp.example.com, your PGP Universal Server must be reachable at

keys.example.com and keys.corp.example.com. If you have multiple PGP Universal Servers in a cluster that are managing an email domain, only one of those PGP Universal Servers needs to use the keys.<domain> convention.

Note: Keys that are found using the keys.<domain> convention are treated as valid

and trusted.

Keys.<domain> should be the address of a load-balancing device, which distributes connections to your PGP Universal Server’s keyserver service. The ports that need to be load balanced are the ports on which you are running your keyserver service, port 389 for LDAP and 636 for LDAPS. You can also name your PGP Universal Server according to your company's required naming convention and ensure that the server has a DNS alias of keys.<domain>.com.

If you are administering multiple email domains, you should establish the keys.<domain> convention for each email domain. If your PGP Universal Server is behind your corporate firewall, you must ensure that ports 389 (LDAP) and 636 (LDAPS) are open to support the keys.<domain> convention.

18 About Naming your PGP Universal Server

How to Name Your PGP Universal Server

Naming Methods

To support the keys.<domain> convention, you can name your PGP Universal Server in one of the following ways:

 In the Setup Assistant, name your PGP Universal Server with the keys.<domain>

convention in the Host Name field on the Network Setup page.  On the Network Settings page, change the host name of your PGP Universal

Server to keys.<domain> .  Create a DNS alias to your PGP Universal Server that uses the keys.<domain>

convention that is appropriate for your DNS server configuration.

About Installing PGP Universal Server

This chapter provides information about the following:

 Setting up your PGP Universal Server  System requirements

Installing your PGP Universal Server For a higher-level view of this process, see Installation Overview (on page 10).

Installation Considerations

You must install and test the installation in a lab or staging environment before you integrate the PGP Universal Server into your network. PGP Universal Server is a customized Linux installation and cannot be installed on a Windows server. Every PGP Universal Server requires a dedicated system that meets the system requirements described in the PGP Universal Server Release Notes. When you install PGP Universal Server, the data is deleted and the system is reconfigured as a PGP Universal Server.

Warning: Before you install, you must back up all the data on the system. The

installation erases all data from the destination disk.

The installation software is included on the Server Installation DVD, which also includes documentation, software license, PGP Universal Satellite and PGP Desktop software installers, and release notes. Symantec strongly recommends that you locate your PGP Universal Servers in secured areas with restricted access. Only authorized individuals should be granted physical access to PGP Universal Servers.

Warning: If you are performing this installation as part of a cluster migration from

version 2.12 SP4, before you begin the migration, you must run the pgpSyncUsers utility on this cluster to ensure the user data is consistent. For more information, see the PGP Universal Server Upgrade Guide for details.

Warning: If you have a hardware token Ignition Key or a Hardware Security Module

(HSM), you must contact Technical Support before you migrate to PGP Universal Server 3.2.0.

Migrating to version 3.2.0 requires that you create a new setting on the upgraded (3.2.0) version of PGP Universal Server before you restore the backup file from your previous system. This setting can only be added through SSH access with the help of Technical Support. If you migrate to version 3.2.0 without adding this preference, you will be locked out of the user interface after the upgrade. As a result, you cannot use your hardware token Ignition Key to unlock your PGP Universal Server.

System Requirements

For the latest system requirements, see the PGP Universal Server Release Notes.

20 About Installing PGP Universal Server

System Requirements

You must install the PGP Universal Server software on PGP Universal Server Certified Hardware. You can find the latest PGP Universal Server Certified Hardware List available on Symantec Corporation's website.

PGP Universal Server on a VMware ESX Virtual Machine

Before you install PGP Universal Server version 3.2.0 on a virtual machine, ensure that:

 VMware ESXi 4.1, Update 1 is installed.  You are an administrator with sufficient privileges to perform the required

functions.  You have used the New Virtual Machine Wizard to create a virtual machine on

the host VMware ESX server with the following requirements:

 Guest operating system is Linux:

 Other Linux kernel 2.6 (32 bit)

This is a required setting.

 Symantec Corporation recommends that you configure at least two virtual

CPUs for PGP Universal Server.

 Have the following as minimums for memory:

 4GB of memory on a single server instance  8GB on a two server cluster configuration  For additional servers, Symantec Corporation recommends additional

memory.

The minimum requirements may also increase depending upon the features in use upon the PGP Universal Servers, such as Gateway Email, PGP Whole Disk Encryption or PGP NetShare.

 LSI Logic SCSI Adapter as the I/O Adapter type.

This is a required setting.

PGP Universal Server does not support the BusLogic SCSI Adapter. If you configure your virtual machine to use this adaptor, a partitioning error occurs during installation.

The remaining options can be configured as appropriate. Symantec Corporation recommends that you configure the VMware hardware as if you were configuring a physical server.

Note: Using PGP Universal Server with VMware VMotion is not currently supported.

Installing VMware Tools for PGP Universal Server

Before you use these commands on the PGP Universal Server, see Using the PGP Universal Server with the Command Line (on page 2).

After installing PGP Universal Server, you must install VMware Tools.

About Installing PGP Universal Server

Installation Materials

To install VMware Tools:

1 Access the PGP Universal Server using the command line with SSH and log in to

the server as root.

To set up command line access to the PGP Universal Server, see the instructions in

Accessing the PGP Universal Server using SSH (on page

21).

2 Run this script:

# /usr/bin/install-vmware-tools.sh --version 4.1

3 When prompted, type reboot.

During reboot, the console messages should indicate that the VMware modules

have been loaded correctly ([OK]). 4 Run # lsmod | grep vm to confirm that the modules have been installed.

This step should list the VMware modules for ESX 4.1. 5 Run the following commands to confirm that the appropriate processes are

running:

 # chkconfig --list vmware-tools

This step shows whether the VMware modules are correctly set to load during system startup. They should be ON for runlevel 3.

 # ps aux | grep guestd

This should show that /usr/sbin/vmware-guestd is running.

Accessing the PGP Universal Server using SSH

To access PGP Universal Server through the command line, you must create an SSHv2 key and add it to the superuser administrator account in PGP Universal Server. You can do this, for example, by using PuTTYgen to create an SSHv2 key and PuTTY to log in to the command line interface. You add the SSHv2 key to your superuser administrator account through the PGP Universal Server administrative interface.

PuTTY is a free suite of SSH tools that includes the following:

 PuTTYgen  PuTTY  PSFTP  Pageant, the PuTTY authentication agent

The PuTTYgen and PuTTY.exe files can be downloaded separately from the Internet. To set up command line access to the PGP Universal Server, see the Knowledge Base.

Gateway and Internal Placement Cluster

You can have a cluster that includes both a PGP Universal Server internally placed and a PGP Universal Server in a gateway placement managing a single mail server, but you should carefully consider why you need both at a single location.

One good reason would be for the PGP Universal Server in gateway placement to act exclusively as a keyserver or as a PGP Universal Web Messenger server, while the PGP Universal Server(s) internally placed handles message processing.

42 Configuration Examples

Gateway and Internal Placement Cluster

The most common usage for this configuration is when you have internal MAPI clients running PGP Universal Satellite in addition to non-MAPI clients using POP, IMAP, and SMTP. In such a scenario, those using standards-based protocols connect to the internally placed PGP Universal Server while the PGP Universal Server in gateway placement ensures proper handling of PGP Universal Web Messenger and Smart Trailer messages for the MAPI clients.

Notes:

If the same user sends messages from different locations (such as from the internal network using a desktop computer, then from a remote location using a laptop), they can create multiple user accounts and/or keys.

The first server (cluster member) is internally placed, with PGP Universal Web Messenger disabled. The second server cluster member is in the DMZ, in gateway placement, with PGP Universal Web Messenger enabled.

Encircled Configuration

Using PGP Universal Server in an encircled configuration is an alternative to placing two PGP Universal Servers in a clustered internal/gateway placement, when you have internal MAPI clients running PGP Universal Satellite in addition to non-MAPI clients using POP, IMAP, and SMTP.

Optional: to hide internal PGP Universal Server IP from outside, use 2nd IP in the DMZ.

44 Configuration Examples

Large Enterprise Configuration

As a large enterprise, Example Corporation has a sophisticated network that includes multiple PGP Universal Servers that are load balanced, PGP Universal Satellite users, a separate PGP Universal Server for PGP Universal Web Messenger and keyserver support, and a standalone Mail Transfer Agent (MTA).

PGP Universal Server Keyserver/Web Messenger Example Corp. DMZ Example Corp. email server F5 BIG-IP Load Balancer PGP Universal Server 1 PGP Universal Server 2 PGP Universal Server 3 MTA Example Corp. internal network Example Corp. email user with PGP Universal Satellite

The company uses its MTA to perform static email routing and to establish rules that govern which email messages are processed by PGP Universal Server and which are not. Naturally, the features of the MTA being used govern what it can be used for.

Note: PGP Corporation does not recommend any specific MTA for use with PGP

Universal Server. Make sure the MTA you decide to use is correctly configured for use with PGP Universal Server.

Spam Filters and PGP Universal Server

Example Corporation has both a content-based and a Realtime Blackhole List (RBL) spam filter that it wants to use in conjunction with its PGP Universal Server. (An RBL is a list of servers that are known to send out spam or to be open relays.)

The company is careful to locate the respective spam filters in the appropriate locations in the logical flow of data and to configure them correctly.

46 Configuration Examples

Exchange with PGP Client Software

Notes:

The content-based spam filter sits between the internal email users and the PGP Universal Server in the logical flow of data so that messages are decrypted before they are checked for spam. This allows even PGP Universal Server–encrypted messages to be checked. Other SMTP filtering devices (such as a standalone antivirus gateway, for example) would be placed in the same location.

Both spam filters must be correctly configured. For example, the content-based spam filter must not treat the PGP Universal Server as a “trusted mail relay” to avoid creating an open relay; this might require disabling the spam filter's reverse MX lookups feature.

For the gateway placement scenario, the content-based spam filter must be configured on the PGP Universal Server as a mail server. This is done on the inbound or Unified SMTP proxy.

With an internal placement, the content-based spam filter is not filtering SMTP, only POP/IMAP, so no special configuration on the PGP Universal Server is required.

Alternatively, put both spam filters between the PGP Universal Server and the firewall in the logical flow of data. This configuration assumes PGP Universal Server–encrypted messages do not contain spam because they are scanned while encrypted. However, spam in unencrypted messages is still detected.

Caution: If you begin receiving encrypted spam, relocate or add another content-

based spam filter to sit between the internal email users and the PGP Universal Server. Receiving unencrypted spam is unlikely because it is CPU-intensive and inefficient.

Note: You might require this alternative configuration if the content-based spam

filter requires reverse MX lookups.

Exchange with PGP Client Software

Microsoft Exchange Server environments (MAPI) are supported in PGP Desktop for internal and external PGP Universal Server users and in PGP Universal Satellite for Windows for external users.

For more information about Microsoft Exchange Server environments and MAPI support, see MAPI Support in the PGP Universal Server Administrator's Guide.

Lotus Domino Server with PGP Client Software

Lotus Domino Server environments, including the Lotus Notes email client, are supported in PGP Desktop and PGP Universal Satellite for Windows for both internal and external PGP Universal Server users.

For more information about Lotus Domino Server environments and Lotus Notes email client support, see "Lotus Notes Support" in the PGP Universal Server Administrator's Guide.

Notes:

This configuration will not work as expected because the mail server will only route outbound email through one of the PGP Universal Servers.

You can use load balancing to achieve a similar result. For more information, see
