DE SMTP on Proofpoint blacklist Friday 12th March 2021 21:19:00
One of the Opalstack DE SMTP IP addresses is currently on the Proofpoint blacklist. We're working to have the IP de-listed and expect this to be complete within the next 24-48 hours.
The DE SMTP IP is no longer on the Proofpoint blacklist.
We're still waiting on Proofpoint to delist the DE SMTP IP address.
