See the NEWS file at
for all the features and bug fixes since 2.1.17.

You have set from_is_list to Munge From. As Andrew says, in 2.1.18 and
beyond, there is a more selective dmarc_moderation_action setting that
does this munging only for post From: a domain with DMARC policy
p=reject and optionally p=quarantine.  Also, at some point (see the NEWS
file for when) this munging was fixed to use the user's real_name list
setting if the display name was not in the email.

You should look at the NEWS for all the things that are enhanced/fixed
since 2.1.17. You should ask for the latest possible version. Note that
the Mailman that manages this and over 300 other @python.org lists is at
the head of the 2.1 branch at
<http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/>. The latest
'official release' is 2.1.22 and 2.1.23 is coming soon.

It is possible, even likely, that your hosting company has installed a
downstream packege (.rpm or .deb) for which there is no upgrade
available. In this case, upgrading may be tricky, but at least if it is
Debian/Ubuntu, see <https://wiki.list.org/x/17891606>, and in any case,
we're here to help.
