I am an admin on a mailman list which quickly had automated spam on it. I moved to having to manually allow new users. Kind of a pain, but stopped the issue. Funny that it took pd-list this long.

Hmm... is this the first time we've seen spam on this list?

seems so.
afaict, the user subscribed to the list this morning, and then posted 
what they posted.
which means, that i don't think there's any systematic exploit which 
would make spam more likely in the future.

in any case, if spam starts to show up more regularly, i might add some 
additional measures (like putting new users on moderation for their 
first post).
i'd rather avoid this, though.
