[Mailman-Users] mailman is very slow...

The "in" directory went empty soon after I created the "null" list (just
didn't add any members)..didn't even have to stop mailman.  I'm looking
at the "archive" directory now trying to figure out why those files are
there.  It looks like it's one list over and over (different one than
what was generating the "deferred" above).  Is there anything to look at
in particular in the message.  Why are they ending up here?  Side note,
it's kind of odd I can't get into the list through the Web interface
using the site password but can see its contents using the command line.
I wonder if the list is corrupt somehow and should be recreated?

Mailman's 'smtp' log is with Mailman's other logs in /var/log/mailman/,
but this is not the issue if you have no files in the out/ queue.

The large number of files in the in/ and archive/ queues indicates you
have a mail loop of some sort or you are the victim of a DOS attack.

Stop Mailman. Move those queues aside in their entirety (e.g. mv
/var/spool/mailman/in somewhere/else), and examine the messages with

See if more /var/spool/mailman/in/ message files are created with
Mailman stopped (new posts will create them even with Mailman stopped)

Once you figure out what's going on, start Mailman.
