Help With Exim Mailer

[Rejean Proulx]

I need help badly.  I can get exim to send external mail.  I can't mail
anything to my local address like rejean at interfree.ca.  It won't receive any
mail from anyone.  I have the IP
192.168.1.0/24 and 192.168.2.0/24 set up  In the log it thinks I am using
192.168.1.1  I wonder if that has anything to do with it?  Here is part of
the log.  I need expert help.  At least someone who is more of an expert
than I am, which might not be hard.

My exim conf is at
www.interfree.ca/exim

It was too big for the list so I had to put it  as a link.  I am out of
ideas on what might be wrong with this.
