Hmmm ... not exactemente ... you can only listne to one IP/port combo.
If the IP is 0.0.0.0, you are listening to all IPs.

How does Apache allow ten web server on different IP's
all to listen on port 80? Answer: you bind to specific
IP addresses instead of 0.0.0.0

Is there a similar mechanism for POP-3?
