Today on August 22, 2022, we added a default SPF (Sender Policy Framework) record to every customer domain name that has Sonic DNS hosting and email hosted with Sonic.
On August 15th, we emailed everyone who would be impacted by this change. The email subject was “Important information about your Sonic domain email hosting” and included a list of domain names that would be updated.
If you did not receive the email or do not have domain email and DNS hosting with Sonic, this notification does not apply to you.
If you received the above notification email and did not opt out or add an SPF record before today, the following SPF record was added to your domain:
"v=spf1 include:mail.sonic.net ~all"
We made this change to fight spam & phishing and to help ensure reliable email delivery for our domain email customers. SPF tells other email providers that Sonic is authorized to send email on behalf of these hosted domain names.
