Hello, End of last week we’ve had DNS problems, resulting in IP blocking issues at Proofpoint. We reached out to Proofpoint (the delisting form) and via email to postmaster. Unfortunately, without any result so far.
Anybody able to share suggestions on how to get in contact with Proofpoint postmaster? Thanks, Ewald Ewald Kessler Deliverability & Abuse Management [cid:[email protected]]<https://www.tripolis.com/>
