I think you will find that qmail-local delivers the original message
to your mailbox, not anything produced by the delivery program you
invoke.  If you want the corrupted message in your mailbox, you will
have to put it there, for example by feeding it to qmail-inject with a
different envelope-recipient address, or by invoking qmail-local
yourself.
