Customizing E-mail Anti-Virus Settings
If you have used the Setup Wizard, you might have already configured the e-mail anti-virus action
and exception settings; the Action and Exception screens allows you to modify these settings. The
Notification screen allows you to specify the e-mail anti-virus notification settings.
Whether or not the STM detects an e-mail virus, you can configure it to take a variety of actions
(some of the default actions are listed in Table 4-1 on page 4-2), set exceptions for file sizes, and
specify which notifications, e-mails, or both must be sent to the end users.
Configuring E-mail Anti-Virus Action Settings
To configure the e-mail anti-virus action settings:
1. Select Email Security > Anti-Virus from the menu. The anti-virus submenu tabs appear with
the Action screen in view (see Figure 4-2 on page 4-6).

Setting Description
Services to Scan
SMTP Select the SMTP checkbox to enable Simple Mail Transfer Protocol (SMTP) scanning.
This service is enabled by default and uses default port 25.
POP3 Select the POP3 checkbox to enable Post Office Protocol 3 (POP3) ). This service is
enabled by default and uses default port 110.
IMAP Select the IMAP checkbox to enable Internet Message Access Protocol (IMAP). This
service is enabled by default and uses default port 143.
Note: If a protocol uses a port other than the standard service port (for example,
port 25 for SMTP), enter this non-standard port in the Ports to Scan field. For
example, if the SMTP service on your network uses both port 25 and
port 2525, enter both port numbers in the Ports to Scan field and separate them
by a comma.
Note: The following protocols are not supported by the STM: SMTP over SSL using
port number 465, POP3 over SSL using port number 995, and IMAP over SSL
using port number 993.
