Enter IP address to test your SMTP server for open relay. If you have an open relay, your SMTP server will be black listed. You can ping your domain to retrieve the IP.

Also...

  • MXToolbox.com - Super Tool. Another great email test site.
  • WebsitePulse.com - Blacklist test. Test if you your SMTP server is on any of the major blacklists.
