Jed.

Here's the intent of using SpamAssassin in mailman:  To handle this [spam] 
problem, I wrote some patches to integrate the SpamAssassin spam filtering 
software with Mailman. With this patch, the majority of the spam sent to the 
list can be discarded without intervention by the moderator.

So, I think either 1)  his patch is not working like we expect or 2) I need to 
tweak the scoring of messages so they are simply discarded, rather than held 
for approval.  I think #2 is the explanation.  The default scores I have to 
hold for moderation are low, so I can bump them up.

As far as the conflict between your setting to drop all moderated messages and 
this spam assassin integration - the spam assassin should supercede this 
option as the scoring should work to discard real spam and send legitimate 
requests to the hold queue.

I'll tweak the scores and watch the results.  I did have a lot of spam and a 
lot of ham to seed the Bayesian databases for each list.

Let me know if you continue to receive spurious results.  FWIW - I haven't 
seen any moderation messages come through for the other lists.
