Forget about tutorials. They tell only a very small part of the story,
mostly without any explanation why a specific setup is chosen.

Use the software's original documentation:

http://www.postfix.org/documentation.html

http://wiki2.dovecot.org

If you have no concept about what you are doing to achieve your goal,
then you should get good books which explain the basics. Setting up a
mailserver (MTA and mail storage/access server) is a tough job these
days because all the things involved (DNS, SSL, DKIM, SPAM fighting
technics) and having a good knowledge about the various RFCs.
