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.
