Check out the rfc's I referred to (1731 and 1734 I _think_...)... They
said something about "apop"... it had something to do with the server
initially giving an identification message like:

+OK Pop3 Server ready <123.45678@xxx.com>

where xxx.com was the host, and 123 and 45678 were the pid of the server
and some other number..

Then the user did a (md4 maybe?) hash of a string consisting of that
server id string plus his/her password, and returned the hash to the
server to authenticate...

Or something like that...
