YES

If you want to make MTA reject messages based on headers then it should be 
done in reply to "the final dot" (otherwise the gain is too little). It 
creates a lot of problems for multi recipient messages - you can only reject 
message to *all* recipients at this stage. Spammers are ready to use/abuse 
every "blind spot".

Some time ago I suggested passing to cyrus sieve parameters available at "RCPT 
TO:" stage for cyrus recipients (connecting host IP and name, envelope sender 
address, envelope recipient address) to allow cyrus sieve reject messages 
before message body is transmitted.

I think that it is worth adding special "envelope-reject" sieve scripts to 
cyrus [previous suggestion was different]
