This is how mailman works.

That is the envelope sender, which is where any not-fully-brain-dead
mail server will send a bounce if the mail can't be delivered.  (this
is different from the From: header)

If you want all of the details, the address works as follows:

  zope3-dev-bounces+garrett=mojave-corp.com at zope.org
  |-------||------|||---------------------|||------|

zope3-dev is the name of the list

-bounces is the suffix added by mailman for the purpose of automatic
bounce handling (mailman uses some 8-10 different addresses for
different list-related purposes).

+ is the delimiter between the actual recipient and an arbitrary
    extension (this is a nice feature supported by many mail servers
    including postfix, exim, and qmail and it fits nicely with the
    spec)

garret=mojave-corp.com is the extension data that mailman wants to
    receive only with bounces caused by the messaged addressed to you;
    it puts an = in place of the @ in your address so as not to create
    problems in the overall address

@zope.org is the domain part of the address


The SMTP server on mail.zope.org is configured to pass messages for
addressed to zope3-dev-bounces in the zope.org domain to mailman's
bounce handling script giving it both the list name and the extension
(which contains the original recipient for whom delivery failed).
