Set

VERP_CONFIRMATIONS = Yes

in mm_cfg.py. This will cause the confirm token to be added to the
From: address of the confirmation as in

From: list-confirm+f901053f30c0fe1b3050899370ed960e6303a68e at example.com

When the reply is sent to
list-confirm+f901053f30c0fe1b3050899370ed960e6303a68e at example.com, the
token is extracted from the To: header and the confirmation is
processed without examining the Subject: header (which contains a
'friendlier' subject) at all.

Notes -

Pre Mailman 2.1.6, VERP_CONFIRMATIONS applied only to invitations.

See the settings for VERP_CONFIRM_FORMAT and VERP_CONFIRM_REGEXP if
your MTA doesn't like the '+' delimiter.
