[exim] redirecting root email

Hey eximers,

I am running exim 4.44 on a debian sarge box and cannot for the life of me
figure out how to redirect mail that goes to the root account to go to a
non-root user. I have tried setting an alias in the /etc/aliases file,
tried setting something in root's .forward file but nothing works. I try
debugging the user routing with exim4 -bt but I have never been able to get
root mail to do anything other than get sent out as root@$DOMAIN....which
is NOT what I want. Any ideas? Would be happy to send more diagnostic
information if I knew of any that would be helpful.

Thanks,

-Cere
