we are using Netscape Messaging Server 3.5
we are now attracked by some hacker using unathorzation use of our e-mail server SMTP service to sent mail bomb to other .
is there any way to disable the SMTP open relay security hole .
I know that it can add a script to the server .
but due to the worst documnetation of the script .
I don't know which command can add to the script to prevent the "Open relay"
is there any example of those script ?
Our server is now black listed by those security org .
so we now can sent ant email to any Public mail server (yahoo , hotmail )
is there any people know how to do ?
