I think it is detectable by the SMTP client that a long return path was
accepted by the receiver MTA or not. After the rejection, a new MAIL
command can be sended with a short return path.


But what happens if the receiving MTA needs to forward its message to
yet another MTA (maybe the receiving MTA was the secondary MX and
needs to forward it to the primary).

In that case, the next MTA could conceivably refuse the message, and
the forwarder would be none the wiser.

I dont understand Your problem exactly. As I understand SPF and SRS the "receiving MTA" will rewrite the return path before forwarding to "another MTA".

(Secondary MX transfer to the primary MX is an other case because primary MX can trust in the secondary MX.)
