I'm seeing a bunch of messages to only one domain on the server in the queue that look like this:

CEF33C61438    10113 Tue Jun 12 09:32:40  sender@example.com
                                                  (mail transport unavailable)
                                         recipient@domainonourserver.com

I found references to Amavis in the archives, but why is this affecting only one domain?

Usually it means you set a wrong transport program for this domain.
You need to check Postfix log file to find more details and figure it out.

All I did was add it through iRedAdmin-Pro, just as I do any other domain.

I guess I will just delete it and re-add it and see if that fixes the problem.
