A fake SMTP server for software integration testing
This is a side project of mine. Use this as your SMTP server in a test environment to guarantee that your users don't receive test emails. Looking for feedback, especially on the security side.

In plain words
A fake SMTP server designed for testing software in development environments. It captures outgoing emails without sending them to real addresses, preventing test messages from reaching actual users. Developers can integrate it into their test setups to verify email functionality safely. The creator is actively seeking feedback, particularly regarding security considerations.

MailFrom.dev – A sandbox SMTP for devs2025 · mailfrom.dev · ▲17Hi HN, Two months ago, we launched MailFrom.dev, a fake SMTP server for developers who want to test email sending without hitting real inboxes – think of it like a simpler, cheaper alternative to Mailtrap or Mailhog with a focus on ease of use. Since then: - We’ve had 55 developers sign up with 4 paid subscription active and 821 test emails sent - Improved stability, speed, and small features our early users needed - Worked hard to add roles (wich will be released later next week) What's improved: - Better UI to inspect headers, bodies, and attachments - Faster inbox refresh and sync between…

Talanoa▲340Hi 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. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
