Oh.. Thats not how I understood it.. I though the S rule only controlled
*WHEN* the rewriting was done (eg, before any address verification or
other checks were done), not what was rewritten..

Upon re-reading the relevant section, I see what I missed.

Grumble.

I suppose I will attempt to make the syntax check conditional, and/or
use a headers add/remove function.

It would still be nice to be able to fix this up before the synax checks
though.. As crappy as these mail clients are, they arent going away, and
they arent going to get fixed, and I would still like to force mail to
have correct syntax..
