You have an SMTP-based filter that takes two minutes to process a
5MB message. See my logfile analysis of a few days ago.
This causes the sender (into the filter) to time out. As per the
SMTP protocol, this is a "temporary" error condition.
The SMTP protocol requires that senders retry delivery after a
"temporary" error, until the message expires in the queue.
