In that case I can really highly recommend it. Nixos on the server is fantastic anyways, and the only hurdle to recommending simple-nixos-mailserver is that most people are not familiar with nix… 😄

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.

Fail2ban allows you set different actions for different infringements, as well as multiple ones. So in addition to being put in a “local” jail, the offending IP also gets added to the cloudflare rules (? Is that what its called?) via their API. It’s a premade action called “cloudflare-token-multi”

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.

Yeah, +1.

I’ve been an avid fan of applocation launchers like rofi and dmenu on the desktop forever, and the “swipe down and immediately search” feels as close as it can get to the mobile equivalent of those.

When I first switched to nix, I made an error copy-pasting my hashed password into a secrets file.

Reninstalled the system 5 times, each time immediately locking myself out, almost

Managing ~35 machines without issues now though.

Noita!

Also the Dead Cells DLCs.

Vikunja seems to check all your boxes

You can even just do Ctrl+A, Ctrl+C, Ctrl+V.

It somehow feels… Wrong, but it just works.

This cannot continue.

• Radicale hosts my calendars and contacts
• zero-hassle setup in Thunderbird for both of those things
• DAVx on Android works seamlessly for calendar and contacts Sync
• Fossify calendar to view, edit calendar
• default contact app for contacts
• Infcloud as a web frontend for Radicale. Not pretty, but absolutely functional (and I hardly ever need it thanks to Android calendar app / Thunderbird)

Haven’t tried todo lists yet, but I would imagine they are similarly hassle-free.

The only annoyance I have is that DAVx is required at all, but I’d suspect that’s an Android/Google issue? IDK.

But anyways, this setup works flawlessly for me.

Thunderbird doesn’t even need a plugin. Just “add new calendar” > “on the network” > enter the URL. Done.

Same for contacts.
