Rspamd seems to get enough data from postfix's milter interface to do
proper and fast antispam filtering and you can extend that with all
kinds of LUA functions. Yes, that's not postfix, but in a way, it's just
a plugin like the others

While I understand your frustration, I wonder what "advanced feature"

I myself am pretty sure that Skynet will start just like this. An AI

What MTAs do not honor this? How does 550 after DATA result in backscatter?
Not returning a 250 OK after DATA is still well within limits of the
SMTP dialog. How else are you supposed to reject a mail that could be
saved because of its size or because it has
quot;unread mails can still be taken out of the users
mailbox". I wouldn't want my postman to fish mail out of my letterbox
just because he thinks my neighbour didn't like it, so I won't either.

nd I sometimes
return mails unopened by adding "return to sender" (and optionally a
reason). I understand that in some countries it's way worse than over
here, but I guess I'd have a stamp then - to have a least some fun while
returning them.
That way I if I mistook a "your
like this in court to have it clarified, but it is something
us postmasters here have to consider.
Perhaps you should too?

And no, I don't do SRS, because I don't want to do workarounds to
support a protocol that was broken by design in the first place.
It's your decision (-all) that you don't want these mails delivered to
the recipients, so I don't really care.

This is a lot easier than forcing any kind of tracking on the senders,
