VERP according to DJB[*] means varying the envelope sender so that
bounces will be guaranteed to include the intended recipient's address
unambiguously.  You need cooperation from the MTA so that it will
accept wildcard recipients.  Most do, but you'd have to configure it
in and have something in Mailman to receive and decipher the bounces.
I may still add this side of things to MM2.1.

Yeah, just because the code in ToDigest.py is not structured to
support it easily. :(
