[Mailman-Users] Delivery to SMTP server very slow

It occurs for all recipients, more or less - sometimes, it gets about
5 recipients done per second, but that's still far too slow.

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.
