Right.

There are various patches for this, but if you're using a local server,
permit_mynetworks is the way to go.
That said, see
<http://mail.python.org/pipermail/mailman-users/2005-October/047086.html>
for one simple patch.
Also see
<http://sourceforge.net/tracker/index.php?func=detail&aid=1798683&group_id=103&atid=300103>.

Mailman can use the sendmail (or other) command to deliver mail. See
the settings DELIVERY_MODULE and SENDMAIL_CMD and their documentation
in Defaults.py, but DON'T DO IT. See the documentation in the
Mailman/Handlers/Sendmail.py module for reasons.
