is rumored to have said:

Fine. You're responsible for delivering mail submitted to you, and
it is entirely reasonable to confirm that the entity you are
accepting it from has provided a usable address. What Postfix then
does to verify it is exactly what would be done if a message was
simply accepted without verification.

Does not take into account the matter of spam with forged headers.

Headers are irrelevant. No one confirms header addresses.

In any case, We are talking about different things. I read the original mail and saw this:

I'm thinking here for example about the Postfix
feature "reject_unverified_recipient"

Which is NOT sender address verification.

Yes, the rest of the text described sender address verification, which is unequivocally bad.
