Easily check the spamablity of your domain and mail server

If you are using your own domain to send emails, you may get the suspicion that your mails may land in the spam folder of your recipients.

MxToolBox is an easy way to check if your domain (or the IP of your mail server) is listed on a spam list.

With MailRadar you can check if you configured your mail server correctly: not allowing others to use it as a relay server.
