Linux Mail Server Solutions are mainly made of MDA (Mail Delivery Agent) and MTA (Mail Transfer Agents). MDA is used to route e-mails to their destination. Dovecot, Cyrus and Courier are some of the examples of MDA. Examples for MTA are Sendmail, Postfix, Exim, etc. Along with MTA and MDA, you will probably need to install a webmail client aka MUA (Mail User Agent) too. Other than the Mail Server configuration, you will need some database setup to store user credentials and related information. Let us take a look at top 3 Open Source Linux Mail Server Solutions.
