If you pass Exim's reverse_host_lookup test, you are off to as good as start as
can be had. Proper HELO/FQDN match added to that is even better.

IF THEN your sender is inappropriately affectionate to the dog w/r header
format, message includes a virus, or other per-user, not per-server rudeness,
the result won't be 'coz your server didn't belong to the right rowing club.

We can't be bothered to check any of the mnemonic-of-the month brainstorms.
As with the crocodile who starved to death on a diet of politicians - there's
precious little substance there once you shake the shit out of them.

Feel free to send me a test message 'direct' if you aren't sure you have it all
in place and doing the expected.

Bill
