Mailing lists munge the From: header so that the message can pass DMARC, since they're often not an authorized sender according to SPF.

I believe one way to avoid the munging would be to not modify the subject (where [sudo-discuss] is prepended) and not modify the body (where the unsubscribe footer is appended) so that the message's DKIM signature matches - although adding those bits to the subject and body are generally considered helpful..

--mark B.

Was wondering earlier what header options this mailing list has.

Most messages have, e.g. "From: Andrew R Gross via sudo-discuss <sudo-discuss@sudoroom.org>"

Yours, @Eric, (possibly because it's a direct reply to me) reads "From: Eric O'Connor <eric@oco.nnor.org>"

Most lists I've been on preserve the original sender in the "From:" header and put the list address in "Reply-to:", which I think makes most sense. But I'm noob at mailing list administration.

I'd like to look into this, put out a "Before vs. after" proposal, make changes if noone objects, and update documentation. If anyone has the foolish vigor to so before me, then my bounty is a tasty beverage at least.

This might be desired, but with it configured this way there is no way to see who an email actually came from on iOS (though many people have a signature or otherwise sign their name).

I'm just trying to see if i fixed the autocomplete error that assigned someone's name to the sudo-discuss email address. Did it work?
