I have a server (perfect Debian with ISPConfig3) that currently has it's POP port set to 110. I have another service that I need to use on this server that needs to be reachable from a VERY restrictive University internet network. I'd like to put this service on port 110 so that it's reachable from the University network. Most of our users use the IMAP protocol anyway, so which files do I need to change the POP port to say port 111? Thanks.
