I'm using Mailman 2.1b3 here and I've been tinkering with the VERP support
too, trying to tie it in with qmail's, so I also went through the changing
+ to - before realising that since I was using a hacked version of
qmail-to-mailman.py I didn't need to... oh well.  Anyway, here's what I
have in mm_cfg.py

VERP_FORMAT = '%(bounces)s-%(mailbox)s=%(host)s'
VERP_REGEXP = r'^(?P<bounces>[^-]+?)-(?P<mailbox>[^=]+)=(?P<host>[^@]+)@.*$'

and I haven't seen any messages about 'unrecognised bounces', though it
hasn't been tested much at this point.

For 'normal' list deliveries though, I've set VERP_INTERVAL to 0 and use a
hacked-about version of Sendmail.py that forces the envelope sender to be
'listname-bounces-@mailhost.dom-@[]' and injects via qmail-inject
