If a forwarder "didn't" strip a signature from the message, after decoding the hash and comparing to the information of the forwarding MTA it wouldn't match anyway, would still invoke some rule on the receiving entity would it not?

This could be added as "middling" comment #6: Signature deletion. A mail forwarder might accidentally or deliberately strip the signature from a message. If the recipient has previously seen signed messages from that origin, then strange behaviour might ensue. Similarly if the recipient is using some policy support like SSP then it might treat the mail less kindly and in a way that'd maybe be hard to figure out. I don't know if this could be a real problem or not (would lean towards "not" I guess) but I suppose its worth thinking about, even if only to give us one "low/low" entry in one of the tables:-) Stephen. _______________________________________________ ietf-dkim mailing list http://dkim.org _______________________________________________ ietf-dkim mailing list http://dkim.org
