My Email Server is an Open Relay

My mail server has been added to block lists on occasion because it was used
to relay spam mail and was reported as doing such. I have spent a lot of
time researching the exchange settings to properly set it to receive and
deliver email without the use of open relay, but to no avail. Under RELAY
RESTRICTIONS, whenever I select "only the list below", I am no longer able
to receive internet email. I do have "allow computers which successfully
authenticate to relay" selected, and have tried many other things to block
the relay without interruption to receiving internet mail, but cannot find a
solution. Any help with this matter will be greatly appreciated.

Windows Server 2003 Enterprise

Exchange 2003 Enterprise

Service Pack 2

Thanks,

HI, settings you made are correct to configure your server as not open
relay, you have just to add your server IP address in the list of IP
permitted to send on default smtp virtual server configuration once set
"only the list below".
In this way you should be able to send and receive mail being not an open
relay server.

bye
