smail -> exim = mail now broken

["Kenneth F. Ryder III" <Kryder71@maine.edu>]

Hi

I am in the middle of setting up my internet mail on my Debian 1.3.1
system.  I was using smail set for "local mail delivered" , and fetchmail
to retrieve mail from my ISP at school.  So local mail worked and ISP mail
was delivered to me too. In looking through the mailing list archives I got
the general feeling that sending mail via SMTP to my school, with smail
would not work, because the FROM: header needs to be rewritten from
"ryder@zeek" ( local machine)  to "kryder71@maine.edu" my internet mail.
Most of the archives suggested exim, so I un-installed smail and setup
exim, just like smail I ran the config program (eximconfig), and setup for
"local mail delivered" option, figuring that I would start there and work
my way up (since that is were I was with smail).  Now mail does not work at
all.  In /var/log/exim/mainlog  it says something like:
	ryder@zeek unknown mail domain , sending error message to root.. ,
root@zeek mail domain unknown message frozen.

Fetchmail seems to be doing its job, forwarding mail to port 25, but exim
gets the mail and has no idea what to do with it....  WHY?   I setup exim
exactly the same as smail, why does it not deliver?  

can some one help me get my mail back so I can move forward with getting it
to send internet mail?

thanks 
	Ken
