Poste.io – full featured mail server installed in Docker container

In plain words

Poste.io is a full-featured email server packaged in a Docker container that deploys in approximately five minutes. It includes SMTP, IMAP, and POP3 protocols alongside built-in antispam and antivirus protection, a web administration panel, and webmail interface. The system uses SQLite for user management and is compatible with external storage, making it suitable for users wanting a self-hosted email solution without deep technical knowledge of email infrastructure.

SMTP + IMAP + POP3 + Antispam + Antivirus Web administration + Web email ...on your server in ~5 minutes You can have a fully functional mail server installed in a few minutes, mostly waiting for scripts to do the work. The whole package is designed with reasonable defaults to get you up and running quickly, without having to know the internals and without making decisions that could break the email system. User data and configuration is strictly separated from binaries. User database is stored in SQLite database - in file. This makes Poste.io fully compatible with external storage.

  Posthorn, self-hosted mail gatewayMay 2026 · github.com · ▲83

  Introducing Posthorn, a self hosted email gateway. One docker container (or Go binary) between every self hosted app on your VPS and your transactional email provider. Set up Posthorn once, point your apps to it, done. I was trying to deploy Ghost on a DigitalOcean droplet and found that DO and many different VPS services have started to block the default SMTP ports to try to combat the various types of abuse they get. To actually configure my app, I had to hack together a Postfix relay. In another project, I had a static site which had a contact form, but my free Formspree account was…

  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. 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…
