50 Configuring Symantec Mail Security for SMTP
Configuring connection and delivery options
To configure SMTP options
1 On the Symantec Mail Security for SMTP administrative interface, in the
left pane, click Configuration.
2 On the Setup tab, under SMTP, in the SMTP port number box, type the port
number for the port on which Symantec Mail Security for SMTP listens.
The default is 25.
If the SMTP port is reset to another port, only email messages that arrive at
the other port will be processed. If a port number is entered that is already
used, the SMTP port number reverts to the previously assigned port
number and a warning message is displayed.
3 In the Maximum number of outgoing connections drop-down list, select the
number of simultaneous connections for outgoing email.
The default is 30. Increasing the default augments the resources that are
required by the program and diminishes performance. Unless you have a
compelling reason to do otherwise, accept the default.
Additional connections are queued when the system is already processing
the maximum number of connections that are allowed.
Multiprocessor computers can effectively use more connections than single
processors.
4 On the Maximum number of incoming connections menu, select the
number of simultaneous connections for incoming email.
The default is 15. Unless you have a compelling reason to do otherwise,
accept the default.
Setting the number of connections too high can slow processing. Additional
connections are queued when the system is already processing the
maximum number allowed.
5 In the Alert/Notification "From:" box, type the text that you want to appear
in the From field when Symantec Mail Security for SMTP notifications are
sent.
The default is Symantec_Mail Security_for_SMTP.
The From field accepts one user name or fully qualified domain address,
which means that the From field can be set to a real account. In this case,
recipients of Symantec Mail Security for SMTP-generated messages, alerts,
and notifications can reply to that account.
