[Exim] Auth again

    Yet another auth question... How can I do next...

    I need auth all users on my server (ip address is unknown and they are
can relay if sender address is *@mydomain.by) and receive mail for this
users from anywhere without auth of couse (without relaying).

    At all there is next... All my clients need auth and all servers no need
auth. Possibly I need two copys of Exim running at server on different ip
and two configure-files?
