I did this myself a few years ago and it was a pain. I always felt on edge thinking things like "What if my postfix server isn't working right now for some reason and I'm missing tons of important mail? I guess I need to set up monitoring now?" IMO, there are email services that cost far less than the time you're going to spend getting it to work. Your home-brewed version isn't going to be as good either. Email today isn't as open a protocol as it used to be. Get used to Google blacklisting your servers for no reason and having no recourse to fix it, and your mail not getting routing to 90% of people. Make sure you at least follow this [1], if you decide to go down the rabbit hole. 1: https://support.google.com/mail/answer/81126 https://support.google.com/mail/answer/81126
