Why don't other mail providers identify the SPF record I successfully created in Route 53?

Short description

The SPF configuration isn't applied with most mail providers because SPF records were deprecated in April 2014. It's not a best practice to use an SPF record. Instead, create a TXT record that contains the applicable values. For more information, see RFC 7208 on the Internet Engineering Task Force (IETF) website.

Resolution

Create a TXT record with the same content as the SPF record:

1. Open the Route 53 console.
2. From the navigation pane, choose Hosted zones.
3. Select the hosted zone where you want to create the records in.
4. Choose Create Record, and then update the following values:
   For Record name, specify the SPF record name.
   For Record type, choose TXT.
   For Alias, keep the default selection of No.
   For Value, enter the SPF record value.
   For TTL, enter the number in seconds. The default value of 300 is typically enough.
   For Routing policy, choose Simple routing.
5. Choose Create records.
