How to verify that my mailserver is not an open relay ??

Hi to all

Unix Serve
If you are testing a Linux/BSD/UNIX server, you can ssh into the box and issue the following command: - telnet relay-test.mail-abuse.org

Windows Server
If you are on a Windows server, you will have to register at http://www.abuse.net/ in order to run these tests/

Thanks for reading
With regards
