Don't forget to set

host_auth_accept_relay = * 

in your global options part of exim.conf

And here's my authenticators configuration part:

############################
#   Authenticators setup   #
############################
 
cram_md5:
        driver = cram_md5
        public_name = CRAM-MD5
        server_secret = ${lookup {$1} dbm {CONFDIR/auth_clients.db}{$value}fail}
        server_set_id = $1
 
end

This example does a lookup for a user: pass combination in a
(dbm) file.

There are more examples of authentication setup for Exim available in the
Exim documentation and the mailinglist archives. See http://www.exim.org
