-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
This (v6) version tackles the character set for header field names issue that Hannah drew attention to. I have also folded in Allen Robinson's BOUNCE draft (fixing it to make the language consistent). There may not be enough there yet as to what needs to be checked -- and I worry a bit about mail that has gone round a loop and through the same machine twice -- it may be a little complex to send the mail back along the forward path correctly... but this does seem fairly exotic... >Internet-Draft draft-clayton-dkim2-spec-06.txt is now available. > > Title: DomainKeys Identified Mail Signatures v2 (DKIM2) > Authors: Richard Clayton > Wei Chuang > Bron Gondwana > Name: draft-clayton-dkim2-spec-06.txt > Pages: 36 > Dates: 2026-01-20 > >Abstract: > > DomainKeys Identified Mail v2 (DKIM2) permits a person, role, or > organization that owns a signing domain to document that it has > handled an email message by associating their domain with the > message.
