In addition to Phillip's comment there is another issue here: how do you do 
deal with multiple recipients? What happens in the case where one 
recipient's script accepts the message and the other does not? In that case 
a 250 has to be returned on SMTP DATA and a DSN sent back for the recipient 
that does not accept the message (the refuse spec does describe that). 
However, the current refuse command only accepts ascii as the reason 
string, and anyone that cares about i18n charset issues will likely want 
the DSN to allow non-ascii.

So to handle the multiple recipient case there has to be a single action 
that can handle both cases: an SMTP error rejection (ascii only) or a 
DSN/MDN (potentially non-ascii) rejection - and the implementation picks 
the appropriate one based on what it is allowed to do for a given message 
and recipient list. Given that I think it makes sense to extend reject 
rather than add a new action.
