What about the most stupid wanabe Spam-fighter which are very

There are a lot of E-Mail Providers (i.e. gmx) behaving like this
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....
