Exim is free software distributed under the terms of the GNU General Public License, and it aims to be a general and flexible mailer with extensive facilities for checking incoming e-mail. Exim has been ported to most Unix-like systems, as well as to Microsoft Windows using the Cygwin emulation layer. Exim 4 is currently the default MTA on Debian GNU/Linux systems. A large number of Exim installations exist, especially within Internet service providers〔Golanski, Y (2000) (The Exim Mail Transfer Agent in a Large Scale Deployment )〕 and universities in the UK. Exim is also widely used with the GNU Mailman mailing list manager, and cPanel. In November 2015 in a study performed by E-Soft, Inc., approximately 53% of the publicly reachable mail-servers on the Internet ran Exim. ==Origin== The first version of Exim was written in 1995 by Philip Hazel for use in the University of Cambridge Computing Service’s e-mail systems. The name initially stood for ''EX''perimental ''I''nternet ''M''ailer.〔Philip Hazel (The Exim SMTP Mail Server (Preface) )〕 It was originally based on an older MTA, Smail-3, but it has since diverged from Smail-3 in its design and philosophy.〔(【引用サイトリンク】title=Philip Hazel's original thoughts on implementing a future MTA based on Smail )〕〔(【引用サイトリンク】title=The Smail-3 MTA )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Exim」の詳細全文を読む スポンサード リンク
