Well the obligatory mention that selfhosting email is more headache than what its worth. You don’t wan’t to be told from expecting recipient that email from you never arrive since their provider blackholed your mail into oblivion.

Try mxroute for email. Currently theres ongoing black friday promo for $15 triennially. https://mxroute.blackfriday/

Not a software project, but eff.org. For software, signal.org.

I’ve also just subscribed to simplelogin premium and i consider it a pseudo donation too since it does have a huge impact on my email management.

Buy from any registrar then use cloudflare as dns hosting. Cloudflare support wildcard catchall email forwarding for free.

Nothing stopping you to decouple both registrar and dns hosting. Its like people doesn’t realize it could be done. Wanting to use cloudflare dns doesn’t mean you got to transfer your domain to them, just change nameserver of your domain at whatever registrar you use to cloudflare nameserver.

Hell you could selfhost your domain zone yourself if you wish so.

Coincidentally thats my setup rn. Hosted my domain dns myself using technitium. Then i further xafr icann root zone and setup dns over tls. The dns over tls queried the local icann root zone copy i got. Its also blocking ads and tracker craps. Basically self reliant dns.

Can be done with bind9 too but i prefer technitium gui than bind9 cli.

Cost and privacy. Currently selfhosting adguardhome. Something like nextdns or controld cost like $35-40/year. Mine cost nothing monetarily since its hosted on oracle cloud free tier. Only costed me like an hour or two of my time to set it up. Plus i don’t trust them enough to not sell my browsing habit.

Windscribe vpn. Got a special account for $10/year. Can’t really selfhost vpn on 100+ location with $10.
