When I migrated our mx boxes from CentOS 5 to 7 I made the leap to postfix.

I built a test server with postfix etc on it and threw everything I
could think of at it before going live.

The key is, like in learning a new language, to start thinking in
postfix terms instead of thinking in sendmail terms.

Exactly, I was about to answer the same.

Postfix has a lot of features build-in Sendmail hasn't. It is feature rich and actively developed. Many things you would need a milter or complex cf style coding for with Sendmail you can configure in Postfix in a simple way.

It takes a while to 'get it' but I'm glad we made the link.

We search, read as many people's howtos as you can (caveat - they are
rarely 100% accurate), and test, test, test before going into
production.

Please, forget about so call howtos or tutorials on the net. They are either dated, giving wrong ideas (no, you don't need a MySQL server to run Postfix), failing to explain why the author has done things the way he writes them up, or they are simply wrong / violating best practice.

Postfix has a very good documentation (compared to the one shipping with Sendmail).
