If you specify a different port number for the mail server, it is possible to use the product and a mail
server in the same computer. The following example uses ports 9025 and 9110 for the mail server.
Because virus scans are performed using SMTP, Internet Gatekeeper does not need the POP
settings, and they can be skipped.
Mail server settings
Change the SMTP server port to 9025, and the POP server port to 9110.
