What do the headers look like? Was the NDR issued by your server, or was it accepted and then rejected farther downstream?

There's no trace of it in our spam appliance logs. What's next? Move the mailbox? I have been Googling (funny how that became a verb!) all morning, but I haven't found much useful information.

One user is getting the same NDR every eleven minutes. I don't see any corresponding events in any of the event logs (2 CAS servers, 2 MBX servers). The tracking logs have Receive (SMTP) /Deliver, over and over - each messageID repeated just twice. Am I right in thinking it's on the other side? Thanks!
