I really dislike that there is this expectation that you have to sub,
but its not true for 99% of our discussion lists. I'd like to plaster
some messages saying "you don't need to subscribe to post here!" in
various places. Yes, I'm all for automatically changing these. When I
did the big dmarc changes, I had planned to do a cronjob to
automatically undo any bad dmarc settings.
To correct these we need to loop over all the lists and check their
config i have some good code to do it and am happy to implement it.
The question I have is, which lists are ok to leave as nonmember=reject,
if any? Announce lists? How about nonmember = discard?
