 |Thank you.

I have a somewhat hard time understanding why greylisting shall be
useful for known domains, unless (maybe) these are somewhat
top-level ones?

As far as i know this "domain.ltd" was already verified by postfix
to be "valid" in the DNS, and then who is this "domain" that you
cannot tell directly whether it is "a malicious player/bot" or
a valid SMTP counterpart?
