At step 2, the receiver can apply spf/HELO tests (or SPF
Lite or CSV or even IP based whitelisting) to bob.mta, and
approve the forwarder based on that.
The receiver can also apply spf/SUBMITTER tests to <bob>,
and approve the forwarder based on that.
Wouldn't this require a PRA check to verify that SUBMITTER is consistent with
the message headers, and wouldn't that be encumbered?
