IMAP Select the IMAP check box to enable Internet Message Access Protocol (IMAP). This service is enabled by default and uses default port 143.

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. 3.

Customizing Email Anti-Virus Settings If you have used the Setup Wizard, you might have already configured the email antivirus action and exception settings; the Action and Exception screens allows you to modify these settings. The Notification screen allows you to specify the email antivirus notification settings. Whether or not the STM detects an email virus, you can configure it to take a variety of actions (some of the default actions are listed in Table 24 on page 85), set exceptions for file sizes, and specify which notifications, emails, or both need to be sent to the end users. 88 | Chapter 4.
