   Is procmail your local delivery agent, or is it mail.local or something
similar?  sendmail can only report the error that the local mailer reports
to it.

   That may not be possible.  The MAIL command has a SIZE parameter, but
unless the remote MTA uses it, you won't know how big the message is until
you have accepted it (for possibly multiple recipients).  Furthermore,
unless you are running a Unix flavor that has compartmental security
(Solaris 10 comes to mind), the defang user may not be able to check other
users' quotas.  And I would not recommend running MD as the superuser.
