DMARCr

DMARCr is a command-line tool for reading and aggregating DMARC (Domain-based Message Authentication, Reporting, and Conformance) reports. It provides a simple way to parse DMARC XML reports and display aggregated data in a table format.

Features

• Read DMARC reports from files or standard input.
• Aggregate data based on source IP, disposition, DKIM, and SPF results.
• Display aggregated data in a table format.

Installation

To install DMARCr, use the following command:

go install github.com/dubyte/dmarcr@latest

Usage

To read a DMARC report from a file:

dmarcr path/to/report.xml

To read DMARC reports from standard input:

cat *.xml | dmarcr

Example Outputs

Assuming you have DMARC reports with data similar to the following:

• Source IP: 192.0.2.1, Count: 2, Disposition: none, DKIM: pass, SPF: pass
• Source IP: 203.0.113.5, Count: 1, Disposition: reject, DKIM: fail, SPF: fail

The output of dmarcr would look like this:

Source IP            Count Disposition DKIM  SPF  
--------------------------------------------------
192.0.2.1            2     none        pass  pass 
203.0.113.5          1     reject      fail  fail
