Mailhardener

What it does

With Mailhardener you can monitor who uses your domain to send email. Not just the legitimate senders such as yourself, your marketing platform, or your automated emails, but also spammers and fraudsters who (ab)use your domain name to scam your customers.

Mailhardener helps you secure and monitor your domain from being used for fraud and spam.

Mailhardener is the best solution to secure and monitor your domain to take full advantage of all email security standards. Mailhardener is free to use for evaluation and non-commercial domains.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
