Hi,
I've also been looking for a variable giving the sender's Email address,
but came to the same conclusion--it doesn't exist. Imho this would be a
useful feature.
I admin a mailing list where I had to set it up to munge the From:
header because of DMARC, and some Email clients--even though they should
know better--were replying to the list even though replies were supposed
to go to the sender. I've since taken advantage of the DMARC moderation
feature, but we've been encouraging people to give their Email address
somewhere in their message. If there were a footer variable with the
sender's Email address, this wouldn't be necessary. Just my $0.02 worth.

We are using version 2.1.16 of Mailman.
The emails that currently are sent out via the listserv server have headers
that include the original sender's email address as the "From:" address.
Yahoo's and Aol's DMARC policy causes these to bounce as our server is not
one they recognize.
I have seen many posts regarding this problem, but no actual solutions that
told me what I should do.
Have you seen the FAQ article at <http://wiki.list.org/x/17891458>.
This is not my area of expertise, just something that dropped in my lap.
A strategy that makes some sense to me is to take ownership of the emails
by identifying the listserv as the From and Reply-To addresses, but
including a custom footer in the email that exposes the actual sender's
email address.
Mailman has various mitigation strategies described in the above
referenced FAQ article. With Mailman 2.1.16, you are limited to munging
the From: header on all list posts, not just those From: domains that
publish DMARC reject and optionally quarantine policies.
2.1.18 adds this latter ability and removes the requirement to add
ALLOW_FROM_IS_LIST = Yes
to mm_cfg.py to enable the from_is_list setting. 2.1.19 has a few minor
bug fixes to the features.
...
I set the annonomous_list setting to yes under general options, and sent a
test email. The email went out fine, but nothing in the default email
footer allowed others to know who actually sent the email out.
Correct. While anonymous_list = Yes will avoid DMARC issues, that's not
what it is designed for.
I attempted to change the default non-digest footer to include the sender's
address, but did not succeed. It appears that this info is regarding the
recipient,not the sender's info.
Correct again. There are no footer replacement variables relating to the
sender.
...
So, the question is how to get the sender's email address in the footer.
You would need to modify the source code, but if you have the ability to
do that, a much better solution is to upgrade to the current 2.1.20
release <https://launchpad.net/mailman/+download> or even the head of
the development branch at
<https://code.launchpad.net/~mailman-coders/mailman/2.1> and use the
dmarc_moderation_action settings for this.
Note that Mailman's strategy is to put the original From: in Reply-To:
or in some cases in 2.1.19+ in Cc: to both expose the address and make
'reply' and 'reply all' work as closely as possible to the non-munged case.
Also note that the development branch is actually quite solid for
production use. It is what we are using for all the python.org lists.
