These messages are coming from Mailman internally, where some outside 
user has tried to spam your list, but instead the message has wound 
up being held for moderation.  Then it's up to you to go through and 
administer the moderator queue at least once a day, for every list.

The alternative is to make the default non-subscriber action to be 
reject instead of holding for moderation.  However, this won't be 
very friendly to real humans who try to post to your list, and you'll 
be sending an auto-response back to the sender address, which is 
probably forged.

This is a "lesser of two evils" choice.  You have to decide for 
yourself and your user community as to what the lesser evil is 
between these two options.
