[Question] Does anyone run their own email server?

DidacticDumbass@lemmy.one to Selfhosted@lemmy.world – 101 points –

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?

I'm using openbsd with dovcot, opensmtpd on a pi. I used mailhardener to get it scoring well. I've had no issues with it getting flagged.

That is cool. This is the solution I was hoping existed, but someone brought to my attention the need for 100% uptime, an by inference the lack of redundancy on a home solution, so I need to reconsider what I am will to do.

I have a friend in a neighboring state that I visit regularly - we're setting up disparate SANs, one at his location, the other at mine. We each get half the storage space; we back up to the half onsite and overnight the onsite SAN data gets backed up to the offsite. This has nothing to do with mail, but if you can host a mail server on something as inexpensive as a pi then you could have one at multiple locations for redundancy purposes.
