To stay on the topic of the list and off the topic of the thread:
You can tell tcpserver which ip address to bind to (see man page). I
have 2 instances of tcpserver controlling pop3, one for each network.
The internal one is not logged and not restricted. The external one is
logged, restriced to IP and limited in the number of connections
allowed.
Your setup most likely grabs the first interface which happens to be
the internal one. Normally (if there is routing between the two) this
doesn't matter. When you have a firewall on the host that blocks port
110, however, it does.
