Two small comments, neither critical I think:

(1) since this is a new email header field, why allow the obsolete
folding-whitespace (obs-FWS)?

(2) under security considerations, you usefully raise the problem of id
harvesting by spammers (or would that be "jammers"? ;).  It occurs to me that
email clients might be encouraged (required?) to NOT disclose jabber-id headers
to any particular recipient without first obtaining the sender's permission (a
bit like the MDN response requirements).
