When faced with sending email from my app, I chose to outsource everything, in order to not learn this stuff..
I set up an account at PostMark (postmarkapp.com), which made it very simple to start sending emails. I did have to change a few DNS settings, but they explained exactly how, and after that everything was a breeze.
I really recommend them to anyone who doesn't want to learn this stuff. It's pretty cheap too (I'm on the free tier so far, but it's a few bucks for a 1000 emails).
