Wrong. I am assuming that sender verification will be done by the mta.
Stop removing the last attribution. Your making this thread harder to follow.

"Wrong." Cut out the attitude will you.
He was responding in a polite way to your vague statement.
"Ok, so I understood it correctly from the start then. Under SPF, the
receiver's mailserver has to know the IP address that the message came from.

Where you actually thought SPF was comparing the original senders IP, when in
fact, it is comparing the IP from the last (sending) MTA.
Go and read the SPF docs and the RFC's for SMTP again. Yes, I'm assuming you
have already read them, even though you don't seem to understand them.
