I've been asked to look into modifying /usr/ucb/Mail, or providing a
replacement for it, so that when a user is sending a message it
verifies that each destination address is valid before passing the
message on to the mailer.  If any destination addresses are invalid it
prompts the user to re-enter them.  Sort of like the 'msg' mailer that
some sites run (ran?).

We'd prefer a mail program that could interface to /usr/lib/sendmail.

The request comes from a user here who's tired of the effort it takes
to detect and resend messages that are bounced back to him because he
mistyped a user name.  I've told him that it would be difficult to
verify remote addresses in real-time, so it's OK with him if only local
users, system-wide aliases, and aliases in a user's .mailrc file are
verified.  Suggestions welcome.
