[exim] Removing Aliases

Hello,

I'm a newbie to exim. I have one glitch that I'm trying to fix and I can't
figure it out.

When I installed my Debian sarge system quite some time ago, it set up
forwarding for my user accounts to another mail account on another domain.
What I would like to do now is to disable that, and just have the mail
reside in the local user's home directory until they fetch it via a mail
client.

rockenfield:~# exim4 -bt root@???
R: system_aliases for root@???
R: hub_user for root@???
root@???
    <-- root@???
  router = smarthost, transport = remote_smtp
  host smtp-server.bogus.com [##.##.##.##]

Any help is greatly appreciated.

Thanks!
