what will postfix do if both missing ?,


I'm sure Viktor and/or Wietse with correct me if I'm wrong, but I'm 
fairly sure Postfix never cares about the presence of a Return-Path 
header *UNLESS* it is configured to strip an existing one out. It does 
not interpret existing Received headers.


postfix drops this header (among others) by default, when processing 
incoming mail:


http://www.postfix.org/postconf.5.html#message_drop_headers


what will spf test do in spamassassin ?


SA has multiple ways of figuring out the RFC5321MailFrom  (a.k.a. 
envelope sender or return-path) value, which the MTA should provide to 
whatever glue you use to integrate SA. Some glue layers (e.g. 
MIMEDefang, MailMunge, and I expect any other milter) construct 
synthetic final delivery headers (Received, Delivered-To, Return-Path, 
etc.) to pass to SA. See the SA docs (and your glue docs, I guess...) 
for details.


SpamAssassin has envelope_sender_header for this use.

other than that, SA supports envelope sender in Received: header which 
postfix supports:

Return-Path should only be added by the final delivery agent. If the 
mail is being sent out to another MTA, it should NOT have a Return-Path 
on it.
