For those of us that have done email for years setting up everything does seem pretty easy. But coming into it cold is hard. New people don't know everything or how it needs to work together.

But, I do remember some useful Linux Journal articles. There may have been a LWN article or two as well.

I do mine on Fedora Linux with Exim, Cyrus IMAP, and SpamAssassin. Exim needs to be configured to deliver to Cyrus properly. At one point I had to adjust the SELinux rules for that but I think that's part of the Fedora packages now. There's also SSL certificate configuration that has to be turned on and adjusted to work with LetsEncrypt.

And then there is DNS with MX, SPF and DKIM and DMARC stuff. And I enabled DNSSEC on my domain which I've heard gives you another few bonus reliability points.

And if you cannot get a static IP then you have to do all of this in the cloud, and optionally configure a VPN and forward your email servers to your home network.
