I tend to agree -- at the point sieve is processing the message, final
delivery has not occured, and thus the headers that are being refered
to here don't really exist yet.

In some ways it is a judgement call.

In any case, the suggested patch would need to handle all of the potential
headers, not just Return-path.  (I still haven't quite settled on wether
to take it or not though).
