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]
