I see in MM2 that regex are used to classify the bounces:
http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/files/head:/Mailman/Bouncers/

which is described in broad terms here:
http://www.esosoft.com/support/mailinglist/mailman/bounce.html

It seems flufl has the same structure http://bazaar.launchpad.net/~mailman-coders/flufl.bounce/trunk/files/head:/flufl/bounce/_detectors/

but I just read the code quickly...
