[Mailman-Users] Possibly OT: VERP to plussed addresses

[Stefan Foerster]

I have noticed that Mailman seems to be capable to correctly parse
bounces that come from a plussed address. Example: I'm subscribed to
this list with

cite+mailman-users at example.net

so the sender address looks like this:

mailman-users-bounces+cite+mailman-users=example.net at python.org

While it's very nice that this is working - _why_ does it work? Does
Mailman simply start at the leftmost "+"?

Oh, and BTW: Happy "1st of a month", python.org listmasters! Enjoy your
bounces ;-)
