Fixing vulnerability requires you to add SPF details on your domain as a TXT record. Your hosting or email solution provider will share the SPF details. If you don’t have one, you may want to check with your hosting provider.
Here are some examples.
v=spf1 mx include:zoho.com ~all
“v=spf1 include:mailgun.org ~all”
If you are using multiple email solutions then you can have all in a single DNS record. The below example covers Google, Mailgun, and Zendesk.
Once you have the SPF details, login to the domain registrar and add them as the TXT record. If you are not sure, you can speak to your provider and they should guide you. However, if you are using Cloudflare then here are the quick instructions.
Login into Cloudflare
Click on DNS tab
Select the type as TXT and enter the details like shown below
It may take a few seconds to propagate and once done, you can test SPF details in the above-listed tools.
Now, my domain is secured from missing SPF and I hope this helps you to protect your email business.
