Does this delay occur uniformly over the entire list, or only within some group of recipients?
It occurs for all recipients, more or less - sometimes, it gets about 5 recipients done per second, but that's still far too slow.
You could try running OutgoingRunner with Python's trace module <http://docs.python.org/library/trace.html#command-line-usage>, e.g.
python -m trace [trace opts] bin/qrunner --runner=OutgoingRunner:0:1
To do this, you'd probably want to stop OutgoingRunner(s), post to the list and then stop Mailman so you have only the one message to this list in the out/ queue, and then run the trace as above, but I would only do this as a last ditch effort, because I'm not sure it would be helpful.
I fear I've got a decision to make here: To "fix" that problem, I'd normally simply export the recipient list and recreate the mailing list thereafter. But since we don't know what causes this behaviour, I can't be sure that my backups include all files I need to recreate that problem on a different machine for debugging purposes.
So, if you are personally interested in this, I would talk to a lawyer to find a way how I can legally provide you with a copy of every file that is in any way related to this list.
If you are not _that_ interested, I'd just go ahead and wipe that list (and cross fingers).
Thank you for your time and your insightful comments.
