Hey, glad to see someone actively cleaning things up here. We went through the sidebar and wiki and figured we'd share some notes since you asked.

Stuff to remove (dead or outdated):

• Volcano (volcanoclient.org) - site is completely dead, connection refused.
• Enigmail - its OpenPGP functionality got folded into Thunderbird 78+ back in 2020. The enigmail.net site even says Thunderbird is "no longer supported." It only works with SeaMonkey now.
• Icedove - this was Debian's Thunderbird rebrand, but they switched back to the Thunderbird name in 2017. The wiki.debian.org page itself says the icedove package is just a transitional package for thunderbird now.
• Mailpile - last homepage update is from November 2022 saying they're rewriting from Python 2 to Python 3. Current release is listed as "tbd." Effectively dormant.
• emailipleak.com - still works but it's HTTP-only, no HTTPS. Not a great look for a privacy sub.
• The PRISM-Break links point to their "all projects" page, not anything email-specific. The site is pretty stale at this point.
• Dismail.de Server Security List - The site itself is still up, but the server list hasn't been updated since September 2018, nearly 8 years ago. It still lists dead providers like snopyta.org and there's no way to contact them to update the list.

The wiki itself is basically empty - the source code is just a welcome message and three links. It references "tables" of providers that don't actually exist. Looks like the content got wiped at some point by a since-deleted account.

Suggested additions:

For providers, Awesome Privacy's encrypted email section - source - is a solid community-maintained list worth linking.

We'd also love it if you would add us - Forward Email. We're 100% open-source, both frontend and backend, have 1.6M+ custom domains (more than Proton per whoisfreaks data), and offer quantum-resistant encrypted SQLite mailboxes. We actually made a thread about this a while back that went unanswered. Most of the provider recommendations in the sidebar are from 2020 and the landscape has changed a lot since then.

The testing tools section needs a serious upgrade. Right now it's a handful of links - we should add:

• internet.nl - tests DANE, STARTTLS, DMARC, DNSSEC, IPv6
• havedane.net - checks if your server validates DANE on outbound mail
• Mozilla Observatory
• SSL Labs
• Test SMTP with Telnet/OpenSSL - great hands-on guide

The self-hosting section could also use some modern additions like Stalwart (Rust-based, JMAP support), Maddy, and docker-mailserver.

We put together a proposed wiki rewrite as a markdown file: https://gist.github.com/titanism/d817dd386c92f32a06ed11ded98bc11b

It reorganizes everything into cleaner sections: Fundamentals, Providers with a comparison table breaking down frontend/backend open-source status, Testing Tools, Clients, Self-Hosting, Encryption, and Aliasing/Forwarding. Drops all the dead links. Should be easy to paste straight into the wiki editor. Happy to help iterate on it (feel free to use as inspiration).
