Those entries are about Postfix receiving the mail for
Kitimat at aqadvisories.ca and delivering it via pipe to
'/usr/lib/mailman/mail/mailman post kitimat' which is passing it to
Mailman for posting to the kitimat list. Presumably the 'mailman'
wrapper received it and queued it.

I don't know where Mailman's queues are in your installation, but based
on logs being in /var/log/mailman, I'm guessing this is RedHat/CentOS
and queues are in /var/spool/mailman. In particular, I think you'll find
the message in /var/spool/mailman/in/*.pck because IncomingRunner is not
running and processing it's queue. Maybe Mailman is not running at all.

See /var/log/mailman/qrunner and points 2.2 and 6.2 at
