Not necessarily. On a small system you could put fowarding signatures on all the mail you send and hope, probably correctly, that the people to whom your users send mail are unlikely to do malicious things with it. >If we ignore unknown tags safely then this extension can be introduced >without any additional issues with the compatibility I suppose. If your DKIM verifier doesn't ignore unknown tags, it's not going to work. People add random tags all the time. I presume you noticed that my draft changed the v= tag so that signatures that depend on forwarding a v=1,tag that is unknown to verifiers that don't implement the draft so they'll consider the signature invalid.
