Sieve is all about policy. A 5xx reject would let the sending server know the message could not be delivered due a failure. (ie: user policy rejection, without receiving MTA generating NDR backscatter). I would rather not just accept it and the message disappear into ether without the sender receiving any notification of why. -- Robert inoc.net!rblayzor http://inoc.net/
