TCP services listen to a TCP port; there is only one "instance" of
TCP on a system, so you can't have two daemons each listening on "its
own IP" but on the same port. There is only one port 110 on the system
as far as TCP is concerned (and similarly, there is a port 110 for UDP).
A really good tutorial on this is RFC 1180 (eg. http://RF.Cx/rfc1180.html).
So, you can either set up the system's IP layer (through ipchains
etc) to redirect connections destined for particular ports on particular
IP addresses to different ports, and then put a POP server on each
of those ports,
or you can set up a single POP server that listens on the port but
acts differently based on the destination IP address of its
connections:

perhaps try perdition (a POP proxy):

Horms: can perdition do this?
