The WG isn't opposed but we have a very long list of nits to clean up so
I'd rather make the list shorter if as in this case it doesn't

That's the conclusion we came to in emailcore. It's so easy to implement
that even though it's been a long time (if ever) since it did anything
useful, it's not worth the

Hi
A good idea in my opinion, additionally add
reject_sender_login_mismatch with maps (u...@domain.ltd user@domainltd)
smtpd_sender_restrictions =
...
reject_sender_login_mismatch,
...
reject_unauth_pipelining,
Than only reject_unauth_pipelining

What I am really missing is clear statements like SMTP-DANE, SPF, DKIM, DMARC
