See my reply in this thread. I think I understand. > This is even more important in Mailman 3 where we've split the pipeline into > rules and handlers.

In MM 3 one can have a rule which checks and verifies signatures and stores results in the msgdata. Than a handler can use that data to add a message header both for recipient info and to inform other bits that might run after there's no longer any msgdata dictionary traveling with the message. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
