To properly evaluate forwarded mail, I believe SMTP sending accounts and SMTP destination domains need to be captured and documented in the message headers, as a message moves from originator to receiver. To make that feasible, SMTP transactions will need to be limited to a single destination domain. In the hope that this concept will someday catch on, I view this document as technology which will facilitate and expedite that imagined future state. Doug Foster
