Most mail servers made of Mail delivery agent (MDA) and Mail Transfer Agents (MTA).  MDA software used to routes e-mail to its destination. MTA software used to transfers e-mail between servers or computers. Apart from these, you need to install and use Antispam, Antivirus, Webmail and other software too. You need to make sure your IP address stay clean. Apart from mail server software configuration, you need to install some database to store user names, email IDs, password and other information. Setting up and maintaining a full-fledged email server is a complicated task.

However, you can skip many of configuration problems and setup complete email solution for privacy and security reasons. So, I am going to list important features of software that can turn any Linux, FreeBSD, OpenBSD or Unix-powered into mail server out of a box with the following goals:

• The software must be open source
• The software must run on Linux or Unix-like server
• It must deploy quickly
• The software setup must be easy for new sysadmin
•  Software must support multiple users and multiple domain names
• Must promote privacy and decentralization
