Reviving an old project to help secure email systems

Years ago, around a decade ago, I managed email servers for a large number of domains. To make this task more manageable and secure, I created some tools to help me verify and monitor email domain configurations. One of those tools was check-maildomain.

At the time, it saved me a lot of time and improved the security of the domains I managed. Fast forward to today, and many email systems are still not configured properly. Misconfigured or poorly secured mail domains are still common problems and risks.

That’s why I decided to revisit my old project, update it, and bring it back. I hope this tool will be helpful not just for me, but also for others trying to harden their email systems.

Cybersecurity has become increasingly critical over the years, and good email hygiene is an essential part of it. Once the first updated version is finished, I hope it will contribute to making the internet safer, one email domain at a time.
