Commit emails to -committers

Greetings folks,

Having had reasonable success with using Reply-To on the -docs and -bugs
mailing lists to have replies go to the correct place while emails come
from the noreply(at)postgresql(dot)org address, we (pginfra) are thinking of
starting to do the same for the automated emails to the -committers
list.

Specifically, we're contemplating something like:

From: Stephen Frost <noreply(at)postgresql(dot)org>
To: pgsql-committers(at)lists(dot)postgresql(dot)org
Reply-To: sfrost(at)snowman(dot)net, pgsql-hackers(at)lists(dot)postgresql(dot)org

being the structure of emails from the commit script.

This would:

- Allow SPF/DKIM/DMARC to all work and be happy, so we don't get email
from -committers being bounced back to us for looking fake.

- Automatically include the committer's email address on replies, as
happens today.

- Automatically have replies go to -hackers (and hopefully eliminate
moderation delays due to folks CC'ing -committers and -hackers)

If this ends up working well and we get to a point where the only emails
going to -committers are the actual commit messages then, we might make
it similar to how -announce is now, where only emails sent from the git
server are accepted and we bounce the rest, to reduce moderator load by
having fewer addresses that spammers can spam us through and which have
to be dealt with. We're not planning to do that right away though, more
a 'down the line' thought depending on how the above goes.

Thoughts? Concerns? Questions?

Thanks!

Stephen
