limit auth to IP

Aloha!
Is it possible to make a decision whether to offer authentication to a
user based on the querying source IP address?
One of the customers is picking up all mail for ~70 users with an
exchange server and plain text POP3 while using criminally simple
passwords, so we would like to limit the logins for just those accounts
to the IP address of that exchange server.
Of course this cannot happen on a firewall level as other customers have
to be able to log in from any arbitrary source IP and OTOH iptables
can't look into the packets to parse the username :-)
TIA
Martin
