What about the most stupid wanabe Spam-fighter which are very
unhappy as in place (e.g. the third-party service provider systems
acting with some SC subsidiaries...) which high rate valid messages
if certain brain-dead conditions like PTR not matching MX
don't match?
There are a lot of E-Mail Providers (i.e. gmx) behaving like this
already.
If A, PTR, MX and HELO are not exactly the same (all four) the message
is marked as SPAM. There are pro's and cons for this...
I would not rate E-Mails solely because of those four points, but
that's only me....
