The DMARC protocol (Domain-based Message Authentication, Reporting, and Conformance), first published in 2015 as RFC 7489, is about to change.

The IETF (Internet Engineering Task Force) has been working on a new updated specification for the past few years. It is internally referred to as DMARCbis and will be published as a Proposed Standard within the next few months.

DMARCwise is gradually adding support for DMARCbis. When you see a “DMARCbis” badge in the user interface, it means that that particular attribute or concept was introduced or changed by DMARCbis.

The current support status of DMARCbis in DMARCwise is:

  • ✅ DMARCbis-specific data contained in DMARC reports is correctly processed and shown in the dashboard as of 28 November 2025.
  • ❌ DMARCbis-specific tags contained in DMARC records are recognized but not extracted, validated or shown in the dashboard.
  • ❌ Hosted DMARC does not allow configuring DMARCbis-specific tags.
  • ❌ The diagnostics feature does not use the new tree walk algorithm for DMARC policy discovery and instead relies on the “old” PSL-based method.
