If dovecot doesn't do it I think you can do it with IP tables.

iptables -v -t nat -A PREROUTING -p tcp -j REDIRECT --dport 23 --to-ports 110

This should make port 23 for example redirect to port 110. I used to use this code to make port 23 act as another port 25.

Hi All

This is possibly a silly question but after reading some of the docs and hunting a bit I could not find an answer.

I need to run my pop3 service on both the standard 110 port and another (not really sure which yet) port.

My ISP is doing shaping on port 110 destined traffic causing a nightmare with some of my machines pulling only some of their mail then crashing (and no its not anything else it is the ISP).

How do I get pop3 of dovecot to bind to two ports?
