Hi I am new here. A sysadmin / dev in Switzerland. Some self promotion of a new project I made for DMARC analysis. Marcan, a selfhosted dmarc analyzer. Single container (rust, sqlite, web ui built in), reads the aggregate reports from an imap mailbox and recomputes spf / dkim alignment itself instead of trusting the reporter. It splits into 4 categories - DMARC pass - Blocked by policy - Forwarded - Delivered failures And lets you analyze the actual failure reasons / failing senders. I made it cuz I had the task to get ahold of our email-security (disaster) and found existing tools lacked the sort of small scale MSP toolset I needed, and paid tools were to expensive for what is needed. It has been in development now for over 2 months, AI assisted, but also continuously tested on the entire set of domains. https://marcan.kaitiaki.tech source: https://github.com/mavgit1/marcan-dmarc #introduction #SelfHosted #DMARC #EmailSecurity #security
