Qmail won't use headers, it uses the SMTP envelope - as all
MTAs should.
If you're dropping a file in the pickup directory, then this
has absolutely nothing to do with RFCs. The MS IIS SMTP service
uses the X-Sender header to set the SMTP envelope, I believe. It's
a hack specific to the MS setup.
This is really an IIS question, but you might want to take a
