How to Run Your Own Mail Server (2017)
I run my own mail infrastructure. To say the least I wouldn't recommend it even to my worst enemies. It's horrible.Actually it's fine until it's not. Then your email doesn't work and you could be missing out on important communications. And then you're scrambling to figure out how the spammers managed to exploit your setup this time. And you have to learn a tonne of crap in order to manage it... and the text files! Configuration... configuration everywhere. Obscure configuration. Configuration that has real consequences and causes spooky action at a distance. Configuration that will soon be exploited in strange ways.I was so frustrated the last time my mail server went down that I started writing an SMTP protocol handler in Haskell with the intent of writing a MTA with the goal of minimizing configuration and being secure and resistant to attacks by default. So that hopefully more people can run their own infrastructure without prematurely aging. I dunno how useful it will be to others but at least it will keep my gray hairs at bay, I hope, when it's ready for use.Until then though we need more guides like this for us poor souls who do go down this route. There are way too many out-dated guides awash in the sea of information.
