Hi,
Two weeks ago I updated Mail security for Exchange from 4.3 from 4.5 and since then quite a few legit senders gets rejected with the reason "sender has spammy reputation (100%)" and gets 100 score.
These two weeks it's been pretty quiet with mail:s during Christmas but almost 1 out of 10 legit mails gets rejected with this reason. Before I upgraded maybe 1 out of 500 legit mails got rejected with this reason.
I dont really know how I can change the settings so this reason not blocking these non-spam mails?
I've checked the real spam that gets rejected by this reason, which are very many, and all of them have also been on DNSBL. So if its possible to not use the "sender has spammy reputation" reason the spam anyway gets rejected as they appear on DNSBL.
Any tips?
