  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.

  MailFrom.dev – A sandbox SMTP for devs2025 · mailfrom.dev · ▲17

  Hi 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.

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…
