Would not it be posiible to interpet only heading sieve rules which reject 
message based on info available at "RCPT TO:" point ?
First "non reject" or "need information not available yet" sieve rule would 
stop "envelope based" sieve rules interpretation.
[ Reject what you know for sure you will reject later - ASAP reject ]

It would be nice to allow sieve reject messages before message body is 
received. IMHO it is worth to investigate achievable gain/cost.
