In the archives of this list I can't find anything on possible checks of $helo versus $ip in filter_relay. What about finding the address of the host given as $helo, and matching it against $ip? Would it be safe to reject the message if they do not match? For instance (not tested in mimedefang-filter yet):
This test has been suggested many times. You will reject plenty of legit mail
if you do it.
If you want to check, put in a test that logs but does nothing else, and check
what it found after a day, or a week. On my site, I could tell it was a bad idea
within an hour or two :-)
