Unspam.email says "There is not a SPF DNS record published for the "from" domain."

Avansare

Hi, I use Sendy, and sent a test email to check the reputation. Using the https://unspam.email/ service, I received the report, all good, but I have a single red alert related to:
"There is not a SPF DNS record published for the "from" domain."

What does it mean? Should I setup something in Sendy?

Thanks.

Hi,

To verify DKIM and / or SPF for your sending domain, please refer to the docs below:

DKIM: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/easy-dkim.html
SPF: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/spf.html

Thanks.

Best regards,
Ben
