I'm running my own mail server for a couple of years now. I'm using postfix and dovecot. I have SPF and DKIM set up and I'm using spamassassin, roundcube.
Setting up a working mail server is one of the biggest challenges because so many components are involved these days and you need to make them play perfectly together. I'm against using out of the box VM images / installers because then you don't understand whats going on under the hood. Mail servers are these kinds of beasts I would suggest to understand as best as possible before letting it loose on the world.
Its like with security. There is no "Just press this button/Just install this software and you are secure" solution - There is no easy and convenient way to run your own mail server without getting really involved with it :)
Just saying this as a warning for everybody who has this thought. I've been through it and my mail set up is running for 5 years like a charm now. But it was a steep way to get there :)
