test failed because your domain does not sign with dkim.

IMHO the rule for mailinglists is simple:

  do not change the subject

  do not change the body (to include "do not add footers")

THen DKIM will still pass, and there is no problem.

I view From: not being the original sender to be a esrious problem as
the "reply" MUA action will send to the list, publishing private
content.   ANd yes, I know about reply-to, but reply-to has become
unusable because so many lists abuse it to cause "reply" to send replies
other than to the original sender.


In all seriousness, just configure the list not to modify messages,
other than adding List-Foo headers, and the problems all go away.
