Postfix is free & open source mail transfer agent (MTA) that routes & delivers Email. It is fast, secure &
easy to administer and is a great alternative to SendMail MTA.

Dovecot is an IMAP and POP3 mail server for Linux. It provides a way for Mail User Agent (MUAs) to
access their mail. Its created to be fast, secure, requires very less administration & uses very less memory
to work.

Squirrelmail provides a graphical interface for sending mail. As you can understand sending & receiving
mail via command line can be bit of a hassle. With the help of Squirrelmail we can open a console in our
web browser for sending & receiving mail.
