Thanks for answering.
Having two mail servers is something we have considered: while possible,
and maybe beneficial for other reasons too, we'd like to avoid the
hassle, if we can achieve the goal in other ways.

P.S.
Clients don't connect to 25; they use 465.
However sendmail currently always pass the messages to
MIMEDefang/SpamAssassin, independent of the port that is used (25, 587,
465).
