This document sets out some basic info on how to integrate our DNS and Dyn Email services with SPF (Sender Policy Framework). For more info on SPF, visit https://dmarcian.com/spf-syntax-table/.
Please note that Dynamic DNS hosts do not support the creation of TXT records, and at this time we do not have any plans to change this.
Dyn Standard DNS
Dyn Standard DNS provides support for SPF via the creation of TXT records in both the ”Expert” and “Standard” interfaces.
If your Dyn Standard DNS zone is configured to use the “Standard” interface (the default), while viewing your zone click the “Add New TXT Record” link and enter:
Host: <blank> Data: "v=spf1..."
If you are instead using the “Expert” interface, in the Add New Record section, enter the following content:
Host: <blank> TTL: 60 Type: TXT Data: "v=spf1..."
Note that the content in the Data field needs to be enclosed in quotes as shown above.
