I recently took over a server (Ubuntu 9) that is set up to send and receive email and uses RoundCube as its webmail interface.
The folks who use the machine don't like RoundCube and want to do everything on their personal gmail accounts. Since RoundCube doesn't support email forwarding (as far as I can tell), I thought that the easiest way would be to download the emails to their gmail accounts via POP3.
I don't know very much about POP3. If the server can send and receive email, does that mean that it probably is able to respond to POP3 requests, or would I need to install something else to do that?
Assuming that my machine has enough to respond to the requests, how do I find out the address where it's serving POP requests? I couldn't find anything in the apache settings, and using nslookup doesn't get me a working address.
