I'm am like 1 week experience with EOP and attempting to whitelist.
I am seeing the infamous 550 4.3.2 dropped messages in my traces. I have added e2ma.net to domain allow list in spam filter under protection. I have also added the listed ip ranges into my anti-spoofing rule as exceptions. (pri 0) I added a rule apply if sender domain is e2ma.net set scl bypass (pri 1). I still am seeing the drop message above. anyone have an example rule/guidance/anything?
I'm not confident I have the last rule built properly. well, I'm not confident I have any of the rules built properly but the anti-spoof seems to work for all BUT emma.
