is there a way to alter pipelines for a specific subset of lists on a 
Mailman list server? at a minimum it would be nice to test the filters 
on a test list before moving it into production. also, some list oweners 
will not want to use such filters.

in reading thru IncomingRunner.py i do not see a simple way to set up 
pipelines on a per list basis, without altering 
IncomingRunner._dopipeline(...) as well.

would running a procmail script on a per list basis be a better way to 
go? i'd rather work with python modules, but i do not want to chop to 
far into Mailman code on the server since only a few lists at most would 
want the extra filtering.

thanks
