Dear Mailcow Community,
can anyone help me with following problem: I have a mailcow instance which always worked like a charm, but suddenly it took like an eternity to receive emails. I noticed that emails show up after a few seconds in rspamd but not in my mailbow. They sometimes take HOURS to get shipped to my Inbox.
What could be the cause here? The Instance once worked perfectly with almost instant receiving mails. Could there be any dns records missing(i recently changed to my own zoneservers).
Thanks in advance
