Coexisting with mail servers
F-Secure Internet Gatekeeper for Linux can operate in the same computer as the mail server. If the
product is implemented in the same computer as a mail server, you must change the IP address or
the normal port number (25 or 110) of either the mail server or the product. We recommend that you
change the port number of Internet Gatekeeper instead of the mail server.
10.3.1
Changing the Port Number of Internet Gatekeeper
If you specify a different port number for Internet Gatekeeper, it is possible to use the product and a
mail server in the same computer. The following example uses ports 9025 and 9110 for Internet
Gatekeeper.
