Hi lovely sysadmin folks. Periodically we've had Mailman => Gmail bounce issues. Last week this cropped up again with a tor-relays@ post from starlight that got rejected by gmail subscribers (such as Nick and me).

Starlight reached out with this tip I thought I'd pass on...

Presently I think a simple config change will help significantly.

If they enable From: "munging" and stripping of DKIM
headers it will eliminate hard SPF+DMARC and in-general
DKIM message failures and spam scoring.  Then messages
from the lists will be judged on the reputation of
the listserv and standard content-based spam scoring,
and not start with a black-mark due to authentication

I'm happy to reply to any questions the admin may have.

Feel free to resolve if we shouldn't go this route. I'll point starlight toward this ticket so he can continue the discussion.

Probably shouldn't do this. We should, however, stop with munging subject lines (and bodies too), and certainly no adding reply-to headers.

Why not? Please expand. Is difficult to follow the reasoning.
