service pop3
{
	log_on_success += USERID
	log_on_failure += USERID
	socket_type = stream
	user = root
	server = /usr/sbin/ipop3d
	wait = no
	disable=no
}

As you see, these are pretty minimal.  Should I try adding an ALLOW line?

I had already changed that from 'yes' to 'no'.

I hadn't really thought about that.  Telnetting localhost 123 makes a
connection, but localhost 110 doesn't.  The problem does seem to be in that
pop3 setup, I think, but I haven't a clue what to do next.
