Dear Clause:

   I will give Drac a try. My idea is to use a binary tree that
requires no file access in order to verify a user. It would be
fast and elegant, though i'd rather not hack sendmail in order
to do it. The map files are a convenient way to talk to sendmail
, though i don't like the idea of continually writing map files when
the data could be cached by a daemon.
