Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I need to run my own email server for some of my domains, because the providers that I usually use don't support them (they use Unicode characters, and not everyone supports that yet). I have a small VPS that I run a few Docker containers on, and I'm wanting to try and run an email server on it as well. What containers are good for a low-hassle email setup? I don't need a mailbox webui (ex: round cube), but it would be nice to have a UI for management. I do need multi-domain support, however.

Stalwart

Written in rust, contains SMTP, IMAP, JMAP, Sieve, CalDAV, CardDAV, WebDAV. Has an admin web ui. Sane defaults, minimal foot guns. No zoo of containers needed.

Beware it's very heavyweight. My dedicated oldish server with 8gb ram and spinning hdes couldn't even handle one single domani and a few users....

Was 6 months ago, tough.

Wow, what a waste!

I had to play with database types, because apparently out of the box setup works only on SSDs (??) And do a bunch of other stuff to improve performance.

End result was way worse than installing postfix+dovecot+dkim/dmark/etc stuff directly.

Quite unusable, but the hardware was limited
