It appears that Sebastian Nielsen via mailop <sebast...@sebbe.eu> said:
just because SPF and DMARC are so badly designed that they can't
handle it doesnt make it "forging" anything.
It isn't badly designed.
Forwarding a email, is the equvalient of, when you receive a signed
envelope from me containing a letter, you forge my
signature on the new envelope.
Sorry, but repeating this doesn't make this any less wrong.

I don't know what you imagine "signed envelope" means in this context
and I'm not sure I want to know.
means dkim signed envelope, that breaks if not using srs ?
The postal equivalent of forwarding
is forwarding, you write the person's new address on the envelope and
drop it back in the mail. It has the same return address because it's
the same letter.

People have been making this victim-blaming argument for 20 years,
ever since SPF was designed in a way that failed to handle normal
forwarding.
when envelope sender domain changes, its a new spf domain to take
responsible of spf, but this will forever be unaligned results on dmarc
It was silly then, and it's no less silly now.
lets make more books on it :=)
This is my last comment on the topic, at least for this round.
we could join another maillist that does not break dkim, in 2024 its
gone more sadly :/
