Although it seems all the qrunner processes are still there, the qfiles seem stuck and until I restart mailman, the queue does not get processed.


Which queues are not processed? All or just out/?

This is malformed spam sent to a list and ignored. It is not related to
your problem.

I'm guessing it's only the out queue that gets stuck. If so, it is
probably because of some glitch in SMTP delivery to your MTA that is
causing the SMTP library routines to hang waiting for an SMTP response
that never comes.

Look in Mailman's smtp-failure log for clues and see the FAQ at
