That's a trivial specific case, of a general problem important in
spamfighting.  While a perfect solution would indeed require an extension
to SMTP, we have ways to approach it.

LMTP would be a fine extension to SMTP, for these purposes.

But why not accept, then later bounce, messages with good DKIM signatures? 
That should be acceptable where the signing domain and return-path domain 
match, should it not? Otherwise, send the notification to the author.
