AFAIK it is an option, but not the default and defaults are rarely 
changed in my experience.

Entirely my opinion, but I suspect that this will be harder to do and 
less portable than having a mailman front-end that recognizes the 
headers inserted by the major spam gateways.

For example, the sites I am aware of run amavisd+SA in front of mailman. 
  They aren't going to disable amavis to have mailman run SA directly. 
Nor are sites with barrucudas likely to do so, etc etc.  My opinion 
entirely, but I think it would be better to make mailman aware of the 
headers inserted by these solutions.

Again, just my opinion.
