That's a VERP probe.

mm_cfg.py should be in the same directory as Defaults.py unless this is
a Debian thing.

You seem to have edited out quite a bit of the grep result :-)
You are running Mailman 2.1.5. VERP probes were introduced in 2.1.5 and
couldn't be turned off. This was recognized to be a mistake, so
beginning in 2.1.6 they are controlled by
VERP_PROBES which defaults to No.
In 2.1.5, you could effectively change the sender of the probe from
gull-annonces-bounces+4ae5d0b7d6547f114afac76d551c9dfbbc3f212e at lists.alphanet.ch
gull-annonces-bounces at lists.alphanet.ch
by changing VERP_PROBE_FORMAT, but this will break bounce processing
because in 2.1.5, disabling a bouncing user relies on receiving a
bounced probe with the token.
Your choices are:
Upgrade (maybe not easy/possible with a Debian package).
Complain to Debian.
Modify Mailman/Bouncer.py to either implement mm_cfg.VERP_PROBES or
just remove VERP probes all together. See
Turn off bounce processing for the list.
