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 Dovecot has an installed base of more than 3 million email servers and a global market share of 68% 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.
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 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.
