[Question] Does anyone run their own email server? (lemmy.one)

All this new excitement with Lemmy and federation has got me thinking that maybe I should learn to run my own instance. What always comes up though is how email is the orginal federated technology.

I am looking at proxmox and see that is has a built in email server, so now I am wondering if it is time to role my own.

I stopped using gmail a long time ago, and right now I use ProtonMail, but I am super frustrated with the dumb limitation of only having a single account for the app. I get why they do it, and I am willing to pay, but it is pricey and I don't know if that is my best option. I guess it is worth it since ProtonVPN is included. It looks like they are expanding their suite.

Is it worth it? Can I make it secure? Is it stupid to run it off a local computer on my home network?

That's right. Also important, email is not a playground for experiments. Once it runs, you should not touch it anymore, except for updates. Otherwise, you will do harm to your own way of communicating. One error, and you will lose all your reputation and someone spams half of the internet with your domain as sender.

An when it runs, the only thing to improve is tuning the spam-filter for your instance. Implementing all the rules that you fight the other day, because otherwise your inbox explodes. So you have to do all the shady things and block ips, filter with blacklists and check every dns for all those extra entries, needed for delivering mail... You must become a part of the problem, spammers all behind every cracked wordpress and insecure vps out there.

Damn, email seems to fragile. I am getting so many perspective, but the main thing that seems like such a gotcha is managing spam, which seems like such a headache.

No, I do not want to become part of the problem.
