They could assess their tolerance for DMARC failures and decide whether to transition from “p=none” to “p=quarantine” or “p=reject.” Introducing the “t” Tag Recognizing the value of “pct= ” to domain owners, retaining this functionality within the DMARC protocol made sense. However, it no longer made sense to maintain a tag named “pct” with only two valid values. To address this, the latest version of the DMARC protocol introduces the “t” tag, which stands for “testing.” The “t” tag has two valid values: “y” and “n.” For more information, you can refer to the official DMARC IETF draft.
The “t” Tag vs. the “pct” Tag The “t” tag was designed Job Function Email List to be analogous in its application by mailbox providers and intermediaries to the “pct” tag values “ ” and “ ”, respectively. Here’s how they compare: “t=y” is equivalent to “pct= ”: Messages marked with “t=y” imply that the domain owner is currently in the testing phase of their policy rollout and the policy is not to be applied by the receiver performing the check. “t=n” is equivalent to “pct= ”: Messages marked with “t=n” will adhere to the default DMARC policy, akin to the previous “pct= ” setting. Read more about the t= tag in DMARC IETF’s official draft.
Implications of the “t” Tag Overall, introducing the “t” tag simplifies DMARC policy handling. While this may initially seem like a minor change, it also streamlines setting and implementing DMARC policies. helps ensure that the policies are more accurately applied, addressing previous issues. Conclusion The DMARC protocol continues to adapt and improve in the ever-evolving email security landscape. Replacing the “pct” tag with the “t” tag is a testament to the ongoing commitment to making.
