Goal: Configure Exchange 5.5 SP2 to only allow E-mail to and from my users,
and disallow any mail to be forwarded via my server (as a relay point) to
2ND Goal: Does anyone know how to filter the logs to find if the server is
routing mail to other domains?
With SP2 you can configuring relay restrictions within the Internet Mail
Service. But the options are confusing and do not appear to address my goal
(see Option Description).
Hosts and clients that successfully authenticate -- Messages sent from hosts
and clients with valid logon information are relayed (BUT HOW DOES THIS
AFFECT INCOMING MAIL?).
Hosts and clients with these IP addresses -- Messages sent from the
specified IP addresses are relayed (WHO WANTS TO SPECIFY IP ADDRESS'S??).
Hosts and clients with these internal addresses -- Messages sent by hosts
and clients that connect to the specified IP address on the Microsoft
Exchange Server computer are relayed.Allows multi-homed servers to restrict
relaying based on the IP address to which the client connects. If you choose
this option, you must disable IP forwarding on the Networking property pages
in Control Panel.
