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?

When I am sending? Well, once things are set up properly I'm pretty confident that things arrive (though nobody can ever be 100% sure of course). I also tend to mail to the same recipient domains a lot, like for work and hobby projects, so once those are tested you get pretty confident.

Unnoticed downtime is usually quickly noticed, I depend on my server for a lot of things. Senders are often resilient enough to keep things in their queue and try a few times. There's also a fallback MX registry at my (3rd party) DNS host which will queue stuff in case the primary MX goes down.
