  • It’s a bit unconventional maybe, but I vote simple-nixos-mailserver - IF you are curious / willing to learn nix. It’s essentially just sanely configured dovecot, postfix, rspamd.

    My config for those three combined is about 15 lines, and I have never had an issue with them. Slap on another 5-10 lines for Roundcube as a webmail client.

    Since it’s Nix, everything is declarative, so should SOMETHING happen to the server, you can be up and running again super quickly, with the exact same setup.











  • We expose about a dozen services to the open web. Haven’t bothered with something like Authentik yet, just strong passwords.

    We use a solid OPNSense Firewall config with rather fine-grained permissions to allow/forbid traffic to the respective VMs, between the VMs, between VMs and the NAS, and so on.

    We also have a wireguard tunnel to home for all the services that don’t need to be available on the internet publicly. That one also allows access to the management interface of the firewall.

    In OPNSense, you get quite good logging capabilities, should you suspect someone is trying to gain access, you’ll be able to read it from there.

    I am also considering setting up Prometheus and Grafana for all our services, which could point out some anomalies, though that would not be the main usecase.

    Lastly, I also have a server at a hoster for some stuff that is not practical to host at home. The hoster provided a very rudimentary firewall, so I’m using that to only open necessary ports, and then Fail2Ban to insta-ban IPs for a week on the first offense. Have also set it up so they get banned on Cloudflare’s side, so before another malicious request ever reaches me.

    Have not had any issues, ever.







  • I have been scrolling on the front page for a couple of minutes now, and I was going to write that it’s literally all conspiracy theories, but that’s not true, there’s also some “sponsored” posts AKA ads sprinkled in.

    What a sad joke.

    If you think the fediverse is too centralized, you can always host your own instance. You get all the same “free speech” benefits (plus no free-speech ban on drugs and porn), without having to put one foot into that cesspit of a site.

    Edit: oh, and that has to be the worst moderation system ever devised - at least if you are a woman or any kind of minority. Good fucking luck in finding a random jury of users who will ever, ever ban a racist or sexist piece of shit on a platform like this. Come to think of it, that’s probably the idea and justification behind the system: being able to loudly proclaim “we have a democratized ban system ensuring moderator overreach is impossible!” does make a great dogwhistle for “you can be a terrible human on here, don’t worry”
