Gotta say, I’m really happy to see so many people here actually talking about doing it! Usually I see a lot of fear-mongering about self hosting email. You can do it, though, and I think we should encourage more people to do so! It can be a little tricky to set up at first because there’s a lot of different things you need to configure and make talk to each other — I haven’t used them but there’s things like mail-in-a-box that are supposed to make this easier. But the most important thing is to make sure you set up SPF, DMARC, and DKIM DNS records (and set up DKIM signing for your outgoing messages). I’d recommend setting the ruf and rua tags in the DMARC record so you get mailed reports from other mail servers (can help you debug if your mail is getting rejected). I’d also use these tools:

Happy mailing :)
Thank you for the encouragement! I am inching my way towards building a server, and I am thankful for all the tips and suggestions I got.
I am starting to think that if email is the hardest to self-host, then perhaps more people should try it. It is worthy to take regain indepedence and autonomy of technology, even if it seen as a lost cause.
Yeah, I hope to get something running soon, just so I can say I did it.
I wish you luck! Some people claim to have troubles sending emails with Outlook blocking whole IP blocks, but it’s a little unclear how much of a problem this actually is to me… it’s a little hard to know if outlook is actually doing this or if people have misconfigured mail servers… In my experience people complaining about this often have a broken dkim key or something. Maybe it’s worth signing up for https://www.dnswl.org/ too, but I’m not sure how big of a difference it makes.
I will definitely look into those things if I run into troubles!
