	At the high school I attended, which uses Kerberos and POP, we
do the following:
following:

1) Add everyone to Kerberos using kadmin
2) Have our public Unix box add everyone to a userdb format file
directing
their mail to user@mailserver.pop (replace mailserver with the first
stem of the hostname)
3) Have the public workstation generate an MH style POP database
without passwords.
4) Have a hack in ruleset 0 of sendmail.cf to direct user@foo.pop to
foo.rest.of.domain.name; if the current machine is
foo.rest.of.domain.name, then run spop username on the message.
5) Have a kpopd running to allow authenticated POP, and a pop3d with
the PASSWORD_HACK option defined to allow insecure usage of POP
pulling passwords from the Kerberos database.

	MIT's system is somewhat more complicated because they have a
rather complicated user database (Moira) and have many more mail
servers.  Also, they don't support the cleartext password POP for most
users.
