DMARC Aide

Domain-based Message Authentication, Reporting, and Conformance (or DMARC for short) Made Easy

DMARC Aide helps you manage DMARC Feedback Reports and offender IPs with ease to help protect your domain from email spoofing and phishing attacks.

Easily parse DMARC reports to identify authentication issues and potential security threats. You can even export a list of malicious IPs for bulk reporting to services like AbuseIP DB.

The app maintains the bookkeeping of an IP List, which will be automatically generated based on the IP addresses encountered in the DMARC report. This list can also be exported as CSV for analytics and reporting.

In a typical use case of DMARC setups rejecting email sender spoofing IPs to impersonate your entity's email, the automatically harvested list of IPs can also be used for black-listing and consideration for further cybersecurity measures.

Don't know what DMARC is or how to set it up? DMARC Aide has some tutorials for it as well - built in to the app itself!

New as of version 2.x: point DMARC Aide at a language model, running locally through LM Studio, on another machine on your network, or in the cloud, and ask it questions about the report you have open. Ask it to summarize the failures, explain a specific IP, check policy alignment, or judge whether a given failure looks like spoofing or ordinary mail forwarding. A built-in DNS utility runs live SPF, DKIM, and DMARC lookups against your domain from inside the app, and offending IPs can be checked against and reported to AbuseIPDB in one click.

If you are setting up DMARC for the first time, DMARC Aide includes tutorials covering how to publish a policy and how to read your first report.
