Hello All, I was wondering if anyone from ProofPoint might be around to assist with deliverability issues for emails coming from my [redacted] domain going to more than a few ProofPoint hosted customers, both enterprise and essentials.
I've checked the IP reputation lookup, but our outbound email shoot out O365 and while /maybe/ there's an IP or two that could be stinky, this has been going on for a few weeks now and every email we send basically comes out of a different O365 IP, so we're thinking this is some type of domain reputation issue? Replies off-list are preferable. Best regards, -joe _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
