🆕 How to conform to Gmail and Yahoo's new requirements for email authentication (DMARC)?
As of 1st February 2024, Gmail and Yahoo have implemented stricter requirements for sending messages to Gmail or Yahoo accounts.
The original announcement regarding these changes was made by Google in October 2023. Since then, security companies have issued warnings that may cause some unease among domain owners. Most of these concerns revolve around the mandatory nature of DMARC. However, it is important to note that this requirement only applies to bulk senders who send 5000 messages or more per day.
If you send less than 5000 messages per day, it is not mandatory for you to publish a DMARC policy.
However, you still have the option to publish a DMARC policy if you wish, even if it is a minimalist (neutral) one. For example, you could add the following DNS record:
IMPORTANT: If you have not yet published an SPF policy on your domain or enabled DKIM signature on your Gandi mailboxes, we urge you to do so as those two authentication methods must be provided in order for Gmail and Yahoo to accept your messages.
