In simple English
Email servers send XML files about who is trying to send mail as your domain. These files are hard to read by eye. This tool collects those files from your email inbox or folders. It saves them in a database and shows clean summary tables. You can run it on your own server for free.
What it is
A self-hosted (software you run on your own server) web application and script collection written in PHP for parsing DMARC (Domain-based Message Authentication, Reporting, and Conformance, a system that stops people from pretending to send emails as your domain) reports.
What it is good for
Website owners and email administrators who want to track email delivery problems and catch spoofing attempts without paying for a cloud service.
- Pulls reports automatically from your IMAP mailbox or local folders.
- Shows clear color-coded tables to spot authentication failures quickly.
- Sends periodic summary reports to your email address.
- Requires a server with PHP, MySQL or MariaDB, and a web server configured by hand.
- Needs command-line access to set up cron jobs for automatic fetching.
- PHP IMAP extension is deprecated, so mail fetching may need extra library configuration.
