Use the check tool
Check with Command Prompt (Terminal)
If you are not familiar with commands, we recommend using free checking tools available on the Internet.

Simply enter the domain of the email address you want to check in your browser and the results will be displayed immediately.

If you're comfortable using commands, you can also look high school coaches email list it up using the Windows Command Prompt or Mac Terminal.

If you're using Windows, enter "nslookup -type=TXT domain", and if you're using a Mac, enter "dig txt domain".

If SPF is set, both results will contain a statement such as "v=spf1".






Three examples of how to write SPF records when setting up SPF!


① Typical example of SPF record
The records required to set up SPF must be written on the DNS server that manages the email address, and the details of the setup method vary depending on the server.

However, in most cases, you will write and configure the settings based on the example below.





v=spf1 ip4: IP address of sending mail server include: domain ~all





For example, if you want to authenticate emails sent from the domain "example.co.jp" and the IP address "192.xxx.xxx.xx", write "v=spf1 ip4: 192.xxx.xxx.xx include:example.co.jp ~all".
