That's not a very safe move. Lots of spammers, for example, target your
secondary (higher MX number) MX host on the basis that it's probably not as
well secured as your primary.

As for your problem of it not scanning the messages, I suggest you briefly
turn on "Archive Mail = yes" so you capture a few messages. Take a look at
the qf file for each one, the sender address is on an "S" line and the
recipient is on an "R" line. I would suspect the domains aren't quite what
you think they are.
