At the moment it can't unless it assumes the order of the signature headers is preserved.
But this is very easy to fix as we discussed earlier. Have a requirement that if a signer adds a signature to a message that already has one it adds in a counter attribute with a higher counter value than any other signature already present. I would also like to see a way for the signer to describe the role in which they are accepting responsibility. It may not be possible to do this in every case but if the signer can say that it is the originator, a forwarder, a mailing list or whatever that will be usefull. > -----Original Message----- > From: Earl Hood [mailto:[EMAIL PROTECTED] > Sent: Wednesday, October 12, 2005 6:53 PM > To: Hallam-Baker, Phillip > Cc: Arvel Hathcock; [email protected] > Subject: Re: [ietf-dkim] Charter bashing... > > On October 11, 2005 at 21:50, "Hallam-Baker, Phillip" wrote: > > > I have a DKIM-SL client that is designed to add an end user > signature. > > How to you distinquish between an end-user signature and a > signature created by a gateway?
