SPF

What is this tool?

This tool will test your domain and determine whether it is using a type 99 SPF record to transmit SPF information to sending mail servers. Please note that this tool will not check for an SPF string as a TXT record.

How do the results help me?

• Mail troubleshooting

If you have a type 99 SPF record in your DNS, use this tool to make sure it's visible and whether the string is formatted correctly.
