domains

The domain name is the key setting for the mail server. An administrator can specify the domains to be processed by the mail server in the administrator console's domain page. The following information should be specified for each domain:

• domain name (in FQDN, Fully Qualified domain Name format)
• Maximum domain size
• Grey Listing mode (one of spam protection methods)
• Plus Addressing mode
• Email address for error messages.

The domain size is calculated as the total size of accounts in the domain. If the total size of accounts in the domain exceeds the maximum domain size, the main server will stop processing incoming mail for that domain.

In the domain settings, the administrator can also specify domain Signature and signature attachment rules and set one or more alternative domain names (alias).

The LDAP Sync option in mail domain settings can be used to synchronize accounts with an LDAP directory, such as the MS Active Directory.

LDAP synchronization

In addition to the local database of mail domain accounts, UserGate Mail Server supports LDAP directories accounts import. This allows centralized accounts management, reduces possible errors and simplifies the administration process. The procedure of LDAP synchronization is described below:

• Enable LDAP Sync in Mail domain Settings - Server Settings
• Specify LDAP name (e.g. Active Directory domain name)
• Specify login and password for the user to connect to the LDAP directory.

You can make additional settings on the Advanced page, such as the name of subdirectory from which the mail server will start browsing through the LDAP directory structure. When synchronizing, the mail server will browse all inferior subdirectories of the LDAP directory.

When addressing the LDAP directory, the mail server will select all accounts that have email addresses in their properties. Directory will be accessed via LDAP protocol. Safe protocol is not currently supported. The timeout for a new request (2 minutes) cannot be changed.
