[imp] Prevent pop3 access

Easiest way is probably to only allow pop3 connections from your IMP 
web server IP address (using tcp wrappers or other method).  Then all
pop3 connections not from IMP would fail, and IMP would still work.

You could do this with IMP, but it sounds like a pain.

I'd use tcp address blocking, or something like that.
