Returning of subject of that thread:

It is funny that working group is managed to make conflict again.
:-)

That what 
	http://www.ietf.org/internet-drafts/draft-ietf-drums-smtpupd-13.txt

suggest to be added to to Received: -line, should be subset of what

	http://www.ietf.org/internet-drafts/draft-ietf-drums-msg-fmt-09.txt

allows to to be included to Received: -line. Actually that is not true :-)


http://www.ietf.org/internet-drafts/draft-ietf-drums-msg-fmt-09.txt allows:

received        =       "Received:" name-val-list ";" date-time CRLF

name-val-list   =       [CFWS] [name-val-pair *(CFWS name-val-pair)]

name-val-pair   =       item-name CFWS item-value

item-name       =       ALPHA *(["-"] (ALPHA / DIGIT))

item-value      =       addr-spec / atom / domain / msg-id


that is almost any name value pair (but only almost.) 


http://www.ietf.org/internet-drafts/draft-ietf-drums-smtpupd-13.txt

says:

   Time-stamp-line = "Received:" FWS Stamp <CRLF>

   Stamp = From-domain By-domain Opt-info ";"  FWS date-time
 
   Opt-info = [Via] [With] [ID] [For]
 
   For = "FOR" FWS 1*( Path / Mailbox ) CFWS
 
Conflict is here. In other words

http://www.ietf.org/internet-drafts/draft-ietf-drums-smtpupd-13.txt

suggest that "for" clause can include several addresses.
However

http://www.ietf.org/internet-drafts/draft-ietf-drums-msg-fmt-09.txt

does not allow that:

name-val-pair   =       item-name CFWS item-value

item-name       =       ALPHA *(["-"] (ALPHA / DIGIT))

item-value      =       addr-spec / atom / domain / msg-id
