It's not simple. I've always found online blogger's tutorials to be a waste of my time. You should be reading only the documentation provided by Postfix.org itself and also your distribution's Postfix specific documentation; FreeBSD, Debian etc. Read both, and make sure you are reading the documentation for the correct versions of both your distro and Postfix. For me, there really were many hours of frustration caused by overlooking the simple gotchas written in bold print in both Postfix's and my distro's documentation. These are often missing from the blogger's tutorials you will find by querying the search engines for "Postfix Configuration How To." Don't try to do it all at once with TLS/Cryus-sasl/Spamassasin/Dovecot on your first attempt. I've always succeeded taking it one step at a time and testing each config change with either telnet or "openssl s_client," before adding more changes. When testing I send test messages to mailinator.com instead of a real email address to avoid being blacklisted for sending too many test messages. Make one configuration change, then test that it works, then back it up. This way you can rollback to a working configuration if the next change fails. Take baby steps; Is the port open? Is it firewalled? Is anybody listening on that port? Is Postfix even running? I've found the simplest way by far to set up a working mailserver is to read the fine manual [RTFM]. Postfix's documentation is excellent. I could kick myself in the head for each time I've goggled for a quick and easy "how to" tutorial instead of reading the manuals. The tutorials never tell you to trun off your partially tested mailserver when you are not actually testing it. Spammers found one of my partially configured Postfix mailservers that I left running overnight on a VPS and sent out 40k plus messages before my VPS was banned/closed and my IP was blacklisted. Ha! Good luck.
