Mail-in-a-Box
Mail-in-a-Box helps individuals take back control of their email by defining a one-click, easy-to-deploy SMTP+everything else server: a mail server in a box.
Project mention: Show HN: Posthorn, self-hosted mail without the mail server | news.ycombinator.com | 2026-05-26A VPS will not be cheaper - but you may get more for your money (more storage, unlimited accounts).
For something simple try https://mailinabox.email/
> would love to switch to some VPS/root or anything where I can SSH and install, compile my own services, but something where security is high and support is 24/7 available.
Those sound like expensive requirements to me. You want managed self hosted email? Some else providing support will be expensive.

Project mention: Proton Mail Suspended Journalist Accounts at Request of Cybersecurity Agency | news.ycombinator.com | 2025-09-12
Not who you asked, but I self-host some non-critical mail domains using Mailu[0], which is a set of docker containers. It's been fairly low maintenance. Ease of setup depends on your technical knowledge, but if I can do it, and you're on HN asking the question, you'll probably manage.

Project mention: We moved all of our collaboration to mailing lists | news.ycombinator.com | 2026-02-05
We have found that people tend to be so used to the quick dopamine hits of chat that they tend to abuse of the availability of chat. Policing is often required to move conversations back to email when things get complex/lengthy.
