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.

does anyone have a good suggestion for running a mail server on my nixos box?

The risk is that the IP will get banned AFTER you start sending out mail from it because it has zero reputation... IT happened to me too and it took months, if not years, to get it definitely cleared. And if you neighbour with a similar IP get infected and start spamming, it's all over again. This is the main issue with residential IPs, it's a very real issue.

To get around it, rent a VPS with a non residential IP and front the mail server there, with tunnels (wireguard+nft) back to your home mail server, so at least the public facing IP is good or has less risks or being blacklisted.
