Port requirements

Symantec Mail Security for Microsoft Exchange scans the SMTP mail traffic that passes through Exchange servers on port 25. Mail Security does not interact with MAPI or any other mail protocols, such as POP3 on port 110 or IMAP on port 143.

Some Mail Security components require certain ports for communication.

Table: Ports used by Mail Security components lists the ports that Mail Security components use by default.

Note:

If Symantec Premium AntiSpam is enabled, ensure that you open port 443 on the firewall for bi-directional traffic to aztec.brightmail.com. If Symantec Premium AntiSpam is not licensed and enabled, Mail Security does not initiate activity on port 443. Similarly, if the optional Rapid Release feature is not enabled, Mail Security does not initiate activity on port 21.

The port that is used for communication with Mail Security Console can be configured during installation or at any time after the installation. You can see activity only on these ports when you use the console to administer a remote server.

Note:

There are no port conflicts or incompatibility between Mail Security and Symantec Endpoint Protection 11.x or the Symantec Endpoint Protection Manager.
