Setting a mail server is easy and hard at the same time. What an irony! Let’s begin with a simple explanation of what is a mail server, why we would want to create one instead of using one of the many paid mail services out there and how much maintenance it requires.

A mail server is the technological equivalent of a post office. It will handle incoming mail by storing or delivering it to the addressed person. This service can be broken in two different types of servers:

• Outgoing mail servers (STMP protocol)
• Incoming mail servers (POP3 or IMAP protocol)
