[Mimedefang] Upgraded SA, now doesnt work

[Jim McCullars]

I've got a wierd one here.  Upgraded SpamAssassin from 2.60 to 2.63 to
start using the SURBL and now no messages are flagged as spam by
MIMEDefang.  I can run command-line spamassassin, even as the defang user,
and read my local preferences file (sa-mimedefang.cf) but emails are not
being flagged.  Hate to admit it, but I'm stumped by this.  How do I start
tracking this down?  Running MD 2.35.
