As of October 3, 2023, Google and Yahoo announced that bulk email senders must have DMARC configured beginning February 2024.
DMARC is implemented using a TXT DNS record. If UltraDNS is hosting your domain, you will need to work with your email service provider for the correct DMARC record syntax and policy configuration.
Important Notes
- DMARC is configured as a TXT record in DNS.
- UltraDNS provides DNS hosting but does not define DMARC policy syntax.
- Your email service provider determines the correct DMARC configuration for your environment.
