Best Linux Mail Transfer Agents (MTA’s) What is a Mail Transfer Agent (MTA)? A MTA is an application that routes and transmits electronic mail from one node on a network to another.

It uses a protocol known as SMTP ( Simple Mail Transfer Protocol) to perform its task. Don’t Miss: On a network node, exists an email client that is used to send and receive messages to and from the mail server, an email client also makes use of the SMTP protocol but it is not necessarily a MTA. MTA’s are installed on a mail server and email clients such as Mozilla Thunderbird, Evolution, Microsoft’s Outlook and Apple Mail are installed on a mail client (user computer).

The site for people who want to establish the Network Server with CentOS, Ubuntu, Fedora, Debian.

In this article, we shall look at a round up of the best and most used MTA’s on Linux mail servers.
