The same as Nancy, I am also seeing viruses (W32Beagle) on moderated
Mailman lists since last Friday, March 5th.  Here are the mbox
headers if anybody has a clue:

In the last 48 hours, two messages with faked (nonmember) addresses 
and virus 
attachments got through to our member-only lists. Between the first 
and second attack, 
I changed the administrator and moderator passwords and I haven't 
shared the new 
passwords with anyone. One of the lists is *very* tightly controlled 
and none of the 3 
folks who could post without moderation has reported their system 
being compromised. 
The logfiles show nothing but the messages going through as if they 
had been from 
unmoderated members of the list (but the sender in the logfile is 
clearly a 
nonmember). I don't see anything in the headers of the messages that 
would indicate 
why they bypassed the moderator.

While this doesn't answer Dean's question about how to compare the 
configurations of 
two lists, my gut is telling me the lists are properly configured and 
something else 
is going on. Any clues would be appreciated.
