[Mailman-Users] troubleshooting out queue backlog

This morning my mailman instance (2.1.9) was not delivering any mail - mail
was going into it but not going out. Restarting mailman and sendmail caused
mail to start flowing again, but several hours later there still appears to
be a backlog of several thousand files in /var/spool/mailman/out - they're
draining, but only very slowly, with some of them dating back to this
morning, around the time of the restart, and mail delivery appears delayed.
I'm not sure if it just needs more time to drain the queue, or if something
is stuck somewhere that needs to be removed - I don't see anything relevant
logged, but I'm not sure if I'm looking in the right place or what I should
be looking for. Can anyone give me any pointers to what i should be looking
at to troubleshoot this?
