Hi everyone

As we all certainly know, this ML since a few months rewrites
all "From:" headers to "X Y via ffmpeg-devel <[email protected]>"
We changed this because neither me nor timo nor rather unhelpfull AI
could fix the bounce & dmarc issue

33 @outlook and 19 @hotmail subscribers got deleted on october 8th
because their accounts where disabled from earlier bounces and they
did not re-enable their accounts.

Other mailing lists from other projects seem to survive without
universal rewriting.

Should we try to switch this list back to only rewrite the
addresses that need it ?

mailman3 has a list where we can manually add domains which need it

hotmail.com and outlook.com both have a DMARC policy of none
so they would not automatically fall under DMARC mitigations
and it seems noone added them to the mailman3 list
nor was outlook in the postfix list we had from mailman2 days

Both me and timo want to try reducing the from rewriting again.
We seem to disagree a bit on if we try with the mailman3 manual
DMARC list empty first or starting with outlook and all entries from
the sender_canonical rewrite list.

Are there any people reading this, who have some information / experiencees
they can share about mailman3 DMARC settings ?
(so we can benefit of your experience and can skip some trial and error :)

What do people think ?
any other thing we are missing ?

PS: we now have a DMARC setup, ARC signing and mailman3

thx
