DNS: Discontinuing the SPF Record (Type 99)
July 28, 2025
update
Our partner DNSimple will discontinue support for the dedicated SPF record type (RR type 99) and transition to SPF records defined exclusively as TXT records, following the recommendations established in RFC 7208.
Accordingly
- We will no longer support the creation or modification of SPF records using the dedicated SPF record type.
- All existing SPF records will be automatically migrated to equivalent TXT records.
- SPF policies will continue to function exactly as they do today, but will be managed exclusively through TXT records.
Starting on August 11, 2025, you won't be able to add new SPF records or modify existing ones using the dedicated SPF record type.
On September 8, 2025, all existing SPF records will be converted to TXT records.
We recommend taking the time to audit any custom code or automation scripts that create, update, or delete SPF records to ensure they're prepared for this transition.
