   Only thing I can think of is, there is something you have to put in
your startup script to make sure that mimedefang gets passed the "r"
option (in my startup, it's MX_RECIPIENT_CHECK=yes).  Also, remember that
when you do a reject in filter-recipient, it rejects the recipient, not
the message (assuming there are multiple RCPT-TO).  I'm not sure how you
tell that it's not doing anything, but here is one test.  Connect to your
backup MX and send mail to someone.  Then look at the sendmail logs for
your primary MX.  You should see a log message that the backup MX made a
connection.

   No, it should just go into filter_recipient.  I must admit, I have
never used that function, only read about it.

   I don't use the confSMART_HOST or the mailertable feature in my
sendmail, so I can't say for sure there, either.

   Good luck!
