Not to handle SPF (though it will check), but just to avoid any
forwarding. It is the fact that our current forwarding node is not
listed by the sender that causes our ISP receiver's SPF check to bounce
the email.

What we need is a mailbox at that forwarding node, so that no
forwarding occurs (instead, we download our emails from that
mailbox), then the SPF parameters of the sender (e.g. Amazon) will not
cause the receiving node's SPF to bounce the email that was previously
being forwarded.
