[Mailman-Developers] Bounce processing in MM3

Barry Warsaw writes:

There are a couple of interesting things in MM3 that makes it different from MM2. In MM3, users and addresses are global to the system, while membership is specific to a mailing list. This means if we register a bounce on an address, we can have that score affect the address's subscription to all relevant mailing list.

That would probably upset users at ISPs that count how many of their addresses are receiving the same message, and bounce them as spam if there are too many. Needs to be an option.
