Not as popular as the others (less than 1% market share).

Config file structure and general operation is less elegant than Postfix or Exim.

Most complicated of the four to install.

According to the Security Space study ( ), in 2019 Qmail accounted for approximately 0.07% of all online public email servers on the internet.

QmailвЂ™s source code was released to the public domain by its author. At its release, Qmail was touted as a more secure replacement for Sendmail. Qmail is an MTA (mail transfer agent) for Unix-like operating systems first developed in 1995 by Daniel J.

Not as easy to configure as Exim or Postfix.

Sendmail was acquired by Proofpoint in 2013. According to the Security Space study ( ), in 2019 Sendmail accounted for approximately 4% of all online public email servers on the internet. At one point (1996), Sendmail accounted for approximately 80% of all public email servers available on the internet. Sendmail is licensed under the Sendmail license. Allman developed Sendmail as a replacement for delivermail for BSD systems, starting with BSD version 4.1c in 1983. Sendmail is a descendant of the original ARPANET delivermail program written by Eric Allman. Sendmail is an MTA (mail transfer agent) for Unix-like operating systems first released in 1983. According to the following study ( ),as of 2019 Postfix accounted for approximately 34% of all online public email servers on the internet. As of 2019, Postfix is still under active development by its creator and a team of contributors.

Postfix is licensed under the IBM Public License. Postfix is an MTA (mail transfer agent) for Unix-like operating systems developed by Wietse Venema in partnership with IBM in 1997.

Arguably more difficult to maintain/administer post-deployment than Postfix.

Easy install, basic install is guided via user interface.

Default MTA on Debian-based Linux distributions.

Exim4 is currently the default MTA on all Debian-based GNU/Linux systems, including Ubuntu. According to the study noted earlier ( ), as of 2019 Exim accounted for approximately 57% of all online public email servers on the internet. Exim is used extensively all around the world. Exim is licensed under the GPLv2 license. This guide focuses on deploying, configuring, and discussing best practices and security concerns for Exim, Postfix, Sendmail, and Qmail.Д®xim is an MTA (Mail Transfer Agent) for Unix-like operating systems first written in 1995 by Philip Hazel.

All three of these email platforms, and Qmail, were originally developed for Unix-Like or Linux based Operating Systems. The top three email servers on the internet are Exim (with over 55%), Postfix (over 30%), and Sendmail (about 4%). However, according to the survey, three types of email servers account for more than 95% of the global market share: Given the long history of email (dating back to 1971), and the massive number of email servers online, youвЂ™d be right to assume that there are many different email server platforms available. According to a 2019 survey from ( ), there are approximately 1.8 million email servers online! The Four Horsemen of Linux Mail Transfer: Exim, Postfix, Sendmail, and QmailД¬onsidering how important and popular email is today, it shouldnвЂ™t surprise anyone that there are millions of email servers currently operating on the public internet.
