An idea (no testing, or real assurance that it would work) would be to
use MD to write a Socketmap (look in the manpage for mimedefang-filter
in the section SOCKET MAPS), then write some m4 for sendmail.cf that
will do the appropriate lookups and piriority/delivery queue/mailer
assignment.  Hmm, perhaps you could define a different mailer DSMTP
(Deferred SMTP) that did what you wanted, then use that for the
affected mail.

Anyway, wild speculation from someone who has never really mucked with
sendmail at that level, but has read about it :)

Cheers,
Austin.
