[Mailman-Users] Trouble Subscribing/Unsubscribing/Sending Messages

[Ki Song]

I must have messed up a setting on my mailman server because none of the
requests sent by email are being processed.

When I send a subscribe request to: specials-join at mail.knifecenter.com I see
my Postfix server relaying the message to the mailman server, but it doesn't
actually subscribe the email address that I want to subscribe. Instead,
there are no actions that are taken by the mailman server (to the best of my
knowledge).

Is there a setting that I could have messed up that prevents messages sent
to the mailman server from being process properly?
