This is not a "pathetic" reply.  This is an RFC-compliant reply.  A user 
agent reasonably expects the To and From header values to match those in 
the initial request.

Why do you need to rewrite the To URI?  The RFC says you shouldn't route 
on it, but on the Request URI.  If you need to rewrite the To URI, 
chances are you are doing something wrong or there is a better way to 
accomplish the goal.
