[Exim] Problem making one users mail go to remote address...

Right now, I'm using a .forward file to make sure that my wife's email
address on our home domain (weller-fahy.com) is delivered to her hotmail
account. Is this the 'good' way to do it? Or should I setup some
combination of special directors/routers in the exim.conf file to make
this happen.

Just wondering...

Regards,
