However, you are mistaken: There is nothing heuristic in the PRA 
identity.  It follows directly from the RFC 2822 definition of the 
headers.  The meanings of From:, Sender:, Resent-From:, and 
Resent-Sender: is in there, as is their relative precedence and the 
ordering issue with Resent-Sender: and multiple Resent-* blocks.

  I stand corrected.  However, Roy's comment about SPF identity (MAIL
FROM) not being available in any reliable way is not accurate, except to
the extent that most MUAs do not display it by default.  It is, however,
easily accessible.  That was my main point.  So to correct myself, both
SPF and Sender-ID identities are essentially equivalent with respect to
how available they are to the MUA (relatively speaking, since no MUAs
currently display either by default).
