Ok, I misread what you were suggesting.  I still really don't see a huge
advantage here, since the great majority of sieve scripts will be based
off of more than just header information.

In any case, it is unclear what could usefully be done with this, as
reject guarantees that an MDN will be sent, which SMTP error codes do not
do.  A discard action has a similar problem -- you still need to accept
the message but later throw it out.
