Postfix is a free and open-source mail transfer agent (MTA) that routes and delivers electronic mail, intended as an alternative to the widely used Sendmail MTA. Postfix is released under the IBM Public License 1.0 which is a free software license. Originally written in 1997 by Wietse Venema at the IBM Thomas J. Watson Research Center and first released in December 1998, Postfix continues to be actively developed by its creator and other contributors. The software is also known by its former names VMailer and IBM Secure Mailer. In November 2015 in a study performed by E-Soft, Inc., approximately 32% of the publicly reachable mail-servers on the Internet ran Postfix. ==Typical deployment== As an SMTP server, Postfix implements a first layer of defense against spambots and malware. Administrators can combine Postfix with other software that provides spam/virus filtering (e.g., Amavisd-new), message-store access (e.g., Dovecot), or complex SMTP-level access-policies (e.g., (postfwd ), policyd-weight or greylisting). As an SMTP client, Postfix implements a high-performance parallelized mail-delivery engine. Postfix is often combined with mailing-list software (such as Mailman). 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「Postfix (software)」の詳細全文を読む スポンサード リンク
