This is on 7.306 Astaro box that's been static for at least a month. All of the sudden this morning this particular Astaro box is bouncing messages from multiple, different, but regular e-mail correspondents. The SMTP logs claim it's due to the RBL dsbl.org. However, nothing has changed on this box configuration wise that we're aware of.
So we unchecked the Astaro supplied "built-in" realtime blackhole list (mainly to drop the dsbl.org) and changed it to some current listings. Nonetheless, the Astaro continues to bounce legit messages from multiple senders. Not a good thing.
Any ideas as to what we should be checking to resolve this issue, or do I need to open a ticket with Astaro?
Thx
