Sadly that is too true.
They screw up greylisting, they screw up SPF and they screw up DMARC.
And to make matters worse, you can easily block IP addresses and IP
blocks of bad email servers.... unless it comes from the rotten lot as
above (including Apple and Microsoft). I see plenty of forwarded junk
coming through my server from Apple and it's a real pain point.
I just wish everyone would stop using those rotten service providers
when it comes to email :(
