Does the SUBMITTER parameter really make sense?
Case 1: The sender is authorized by some domain to
send messages. The message will have to be accepted and therefore
to be transmitted. No benefit in checking the parameter before
transmission. Could do this also after transmission.
Maybe, maybe not. Having the information early might in some MTAs
allow for
throughput optimizations.
You are proposing an optimisation of what will become the rare failure
case. That's like optimising printing the 'bad password' message. It
never
happens.
The advantage to SUBMITTER is more obvious in combination with
reputation and accreditation. It lets you start the
accreditation/reputation check early, either before accepting data or
in parallel with the PRA check in the headers.
