[Mailmunge] Weird timeout issue.

Any idea what this is all about?

Mail right before and right after were accepted no problem.
It appears something with this sender is causing something to happen.
This happened multiple times, each time this same sender retried sending the same timeout happened.
But every other mail was accepted and processed by mailmunge without issue.
