Professional service and support for Dovecot

Dovecot is a free IMAP and POP server that was developed with a special focus on security. It is a streamlined, fast, and easy-to-install mail server. Dovecot supports mbox and Maildir, and also provides an as yet still experimental, native and high-performance format called dbox for storing emails. The software contains a mail delivery agent for local delivery, which can also use the Sieve programming language for filtering. Dovecot offers a range of authentication methods. The server can operate on GNU/Linux as well as other unixoid operating systems.

Dovecot is free software, the source code is available on the project page .
