Figure 6-1

2.In the Email section of the screen, select the protocols to scan by selecting the Enable checkboxes and enter the port numbers if different from the default port numbers:

•SMTP. Simple Mail Transfer Protocol (SMTP) scanning is enabled by default on port 25.

•POP3. Post Office Protocol 3 (POP3) scanning is enabled by default on port 110.

•IMAP. Internet Message Access Protocol (IMAP) scanning is enabled by default on 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 UTM: SMTP over SSL using port number 465, POP3 over SSL using port number 995, and IMAP over SSL using port number 993.

3.Click Apply to save your settings.
