headers as described in [SENDER-ID]. If this purported responsible
address does not match the address appearing in the SUBMITTER
parameter, the receiving SMTP server MUST reject the message using
"550 5.7.1 Submitter does not match header."
So there is an ordering here:
- First, the receiver checks the to see if the SUBMITTER domain passes
the Sender ID check.
- Second, if the receiver decides to accept message data (either because
SUBMITTER passed the check, or because SUBMITTER failed the check but
the receiver decided to accept message data anyway) then the receiver
should ensure the SUBMITTER value matches the PRA and reject if there's
