Without requiring a check (not saying what action the receiver must
take) of the From address, what we are saying is that bad guy signature
on evil nasty email is just as worthwhile of a signature as that of the
owner of the domain in the From address.
I supose that's often true, given that a signature from a random
unknown sender that matches the From: address is just as worthless as
a signature from a random unknown sender that doesn't match the From:
address.
But please stop misrepresenting other people's arguments. Nobody has
ever claimed that a random signature gives mail a free pass.
