But there is a small problem. It is rather polical.
We have a telecommunication law that allows ISPs to discard
forged email, but our Ministry so far does not acknowledge
that failure of DKIM verification immediately equals to
forgery, because there could be other reasons to fail.
There are technical and operational reasons that can cause legitimate mail
that was originally signed with a legitimate DKIM signature, to fail to
verify.
The fact that a signer signs all their mail does not mean that all their
mail will arrive with a valid signature.
Simply publishing an ADSP record does not change this fact. ADSP can
perhaps be used productively for specific signers and verifiers, but it
does not work for all legitimate scenarios.
What does work for all legitimate scenarios?
