You're right--4xx does not increase the bounce counter. That leaves only 
the 5xx.

Well, I can't argue that in this instance free.fr does a better job of 
detecting spam than the list, but a) free.fr does not provide mailing 
lists beyond the most basic functionality, and b) I'm not in position to 
suggest moving the list as I'm not the owner, only a member.

Regarding your suggestion of better spam detection at the earliest 
stage, I agree wholeheartedly. But while I might be able to suggest 
mailman settings to the list owner, heavier actions such as changing the 
spam detection methods in place on the list are out of question.
