[Mailman-Users] Held for Implicit Destination

I'm starting to get quite a few of these and have no clue why. It was working a few days ago...

Ok I have more information now. I have a list that works (test) and a list that dosen't work (CapeCodGroup), I'm subscribed to both and they both have the same administrative options: http://patternstudy.com/mailman/admin/

When I send mail to the first list, it goes out to the recipient list (me). When I send mail to the second list, it is held for Implicit Destination. ?

The administrative password for these two lists is 'password' in case someone wants to have a look.

What does mailman look at to determine the 'implicit destination' ? Is it in the headers?

Confused,
