That line tells Exim which hosts it should allow to relay if those
hosts present authentication. A summary of the relevant options is:

hosts_accept_relay = <list of hosts you trust to relay without auth>
hosts_auth_accept_relay = <list of hosts who can relay if they authenticate>

The former will probably include localhost and your local network.

The latter can be '*' if you don't know where your authenticated
clients are coming from.

Please, upgrade to Exim 4 - you'll get much more help. Your software
is over 2 years old.
