I would think that the right solution would be to make smartsieve
know about the envelope extension and have it explicitly offer
comparisons against envelope sender and envelope recipient rather
than the Return-Path and possible Envelope-To headers.

So you wind up with sieve scripts that won't work as expected on other
conformant sieve implementations.
