I sign no mail==I only sign other peoples mail (third party signer) I sign some mail==I sign some mail from my domain but don't want to be sued for you getting unsigned spam purportedly from me.

The recipient will not look at the policy record if there is a valid signature and if there is no signature the fact that it might have been signed is irrelevant. The only policy that has use to a recipient is to know that every message without exception is signed. Otherwise there is no utility in the policy record. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Wietse Venema > Sent: Thursday, September 07, 2006 7:23 AM > To: [email protected] > Subject: Re: [ietf-dkim] user level ssp > > Hallam-Baker, Phillip: > > I think it is entirely likely that bigbank.com would have a > situation > > where the mail servers for its east coast offices were adding > > signatures but the ones for the west coast were not.
