Postfix is a very large and complicated piece of software. I doubt you'll find adequate help in setting it up here. If you're administering a very large environment, it's definitely worth taking the time to learn. Otherwise, it's probably way easier to use something like msmtp to send mail instead. The documentation for that project is much more manageable (and in fact you probably don't even need to read it - just modify the example config file that comes with it). Just give it your login information and configure mail or mailx to use it.
