Glenn - Wrong answer.  Thank you for playing.  You are assuming that
there is some correspondence between /etc/passwd and the maildrops on a
system.  Poor assumption.

Skip - look at the POP server in MH 6.8.3, which implements APOP.  If
you use popper instead, then there are mods to that available as well.
