I just went through exactly same thing....

#!/bin/sh
echo "+OK QPOP (version 2.53) at bsd1.nyct.net starting."
read -t 10 INP
echo $INP >> /var/log/wrongpops
echo "+OK Password required for $INP."
read -t 10 PAS
echo "-ERR Change your popserver to mail.nyct.net."
echo "+OK Pop server at bsd1.nyct.net signing off."


This is what I ended up with . It also logs usernames, so you can
track users with wrong POP server information. Also note the timeout of 10
seconds on reads - helps a lot ;)

The only problem I saw was with some versions of Eudora, it freezes up.
