Thank you. I'm not a fan of munging addresses. Please remove all munging
as much as possible. We have a few much less used domains with lists, if
you could add them to the list of things not to munge:
endsoftwarepatents.org, fsf.org, defectivebydesign.org.

Related thoughts:

Some of our lists do their own munging, either because the list admins
set it up that way (FSF are site admins in Mailman terminology), or
because they have a special requirement, but last year I adjusted all of
the lists so that the type of munging would pass dmarc. I'll do another
check to make sure they are all good.

Let me know if you have any other questions.
