I don't see the value here.  Why would a client be configured with the
address of an SMTP server that is something _other_ than its submit
server?

If you do decide to go forward with the I-D, though, you certainly need
to add information on what a client is supposed to do if it can't
resolve the information provided in the SUBMIT response (such as 
unknown URI or unresolvable DNS hostname).  Should the client ignore
the ever-so-gentle request to not use that SMTP server as its submit
server and just go ahead and use it anyway, or ?
