Dovecot is an open-source IMAP and POP3 server for Linux/UNIX-like systems, written primarily with security in mind. Timo Sirainen originated Dovecot and first released it in July 2002. Dovecot developers primarily aim to produce a lightweight, fast and easy-to-set-up open-source mailserver. According to Openemailsurvey 〔(【引用サイトリンク】 title=Open email survey )〕 Dovecot has an installed base of over 2.9 million email servers all over the world and a global market share of 57% of all IMAP servers. While Dovecot software can be used in commercial use without any license fees, a commercial version is also available as Dovecot Pro. The commercial version is provided by Dovecot Oy along with support and enterprise add-ons such as the object storage and full-text search plugins. Since March 2015, Dovecot Oy has been part of the Open-Xchange Family. ==Features== Dovecot can work with standard mbox, Maildir, and its own native high-performance dbox formats. It is fully compatible with UW IMAP and Courier IMAP servers’ implementation of them, as well as mail clients accessing the mailboxes directly. Dovecot also includes a Mail delivery agent (called ''Local delivery agent'' in Dovecot’s documentation) and an LMTP server, with optional Sieve filtering support. Dovecot supports a variety of authentication schemas for IMAP and POP access including CRAM-MD5 and the more secure DIGEST-MD5. With version 2.2 some new features have been added to Dovecot, e.g. additional IMAP command extensions, dsync has been rewritten or optimized, and shared mailboxes now support per-user flags. Apple Inc. includes Dovecot for email services since Mac OS X Server 10.6 Snow Leopard. 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「Dovecot (software)」の詳細全文を読む スポンサード リンク
