5
z Multiple Domains
Up to 10 mail domains can be created on ES-6000 and work properly simultaneously. Each mail
domain can have its own mail account as well.
z Anti-spam
Built-in with Bayesian, fingerprint, verifying sender account, checking sender IP in RBL and else
anti-spam system work to filter spam mail automatically.
z Anti-virus
Built-in with Clam AV and Sophos scan engine can filter malicious program in mail content, to
prevent mail receiver from virus threat. The virus pattern can be updated regularly, and without any
license fee.
z Mail Audit / Archive
User can define rule (such as keyword, sender, receiver, size…) for mail audit, when the incoming or
outgoing mail matches the rule, then system will handle the mail based on the rule to pass, delete,
inspect, delay, or copy to a specific account.
z Mail Account Learning
Built-in with mail account learning system, such as Automatically Adding, Query Old Mail Server, or
LDAP, user can migrate mail account from old mail server, or create new mail account quite facile.
z Shared Address Book
Shared Address Book function not only works for Web Mail users, it can also connect to mail client
software with LDAP service, such as Outlook Express, to search the destination address within
Shared Address Book.
z Customize mail account
Each mail accounts can be customized quite precisely based on company’s policy, such as to enable
or disable Mail protocol, Mail size limitation, Mail box Quota, Personal web disk quota, and Push Mail
quota.
z Web Server
ES-6000 not only provides mail server function, it also offers web server function to allow user
creating company’s website on same device. So user will not need to purchase further software or
hardware for web service.

Built-in with DNS server, administrator can setup the domain name resolution by himself, and will not
need to spend money to deposit DNS service at ISP.
z Remote Backup
ES-6000 will record every passing mail as the record, and backup the record to NAS or File Server
by schedule. Those mail records can also be retrieved from NAS or File Server via ES-6000.
z HA
Built-in with HA (High Availability) function, the stored data can be synchronized with two ES-6000
devices, to prevent losing mail while mail server is damaged.

domain alias and mail relay.
Mail setting:
Determines of which cryptographic method and port number will be used in each service
Assigns a port exclusively for logging to web mail interface.
Allows email account registration from the Web Mail login screen
Apply the physical IP address for sharing files in web disk.
Determines the maximum amount of simultaneous connection of sending mail.
Determines the maximum duration of a mail lifetime in Queue.
Restricts mail delivery services with local SMTP authentication.
Auditing outgoing mails for security’s sake with mail gateway

4.1.1 Setting
Mail Setting Definition:
TLS + SSL:
Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic
protocols that provide secure communications on the Internet. There are slight differences between SSL and
TLS, but the protocol remains substantially the same. However, TLS used to operate at transport layer, which
now has changed into alternations between application layer and transport layer. (Figure 4-1)
Figure 4-1 Email Setting
26
Reverse DNS lookup:
Reverse DNS lookup determines whether a domain name is associated with the sender’s IP address.
Block Dictionary attacks:
A dictionary attack is an attack which uses a dictionary to randomly generate email addresses that are
directed to the same domain.
Account Request Setting:
ES-6000 allows users performing account registration from the Web Mail login screen. If this feature is
enabled, it is recommended to set the Account Request Setting to Approval by administrator; If set to No
approval needed, then the device might be compromised to send spam.
Max. message queueing time:
What if users’ mails failed the delivery, the mail will save in ES-6000 queue and waiting for the next delivery.
Users can define the lifetime of mail in queue, when the lifetime is end, the mail will be removed from queue
and return a failure notification to sender.
SMTP recipient limit:
The value for SMTP recipient limit will affect the system performance. It is not recommended to set a value
to more than 100.
Enable Local SMTP Authentication:
When SMTP authentication enabled, users must meet one of the requirements listed below to process mail
delivery.
1. Either sender's source IP address or recipient's domain name must exist on the Mail Relay list.
