Hi:
	I haven't seen this discussed here before and I have had some
requests from users who want to connect to a pop mail server that is
on the untrusted side of our firewall.  Are there any proxy servers 
available for pop mail?  What implications would there be in opening up 
ports 109 (pop2) or 110 (pop3) on the firewall and routing the packets
through?  Is this even possible?  One concern would possibly be with 
address spoofing I suppose but I believe we have that covered with the
router (on the untrusted side) not allowing source routing.  Am I wrong?
Any help would be much appreciated.
