What is Dovecot?

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.

Dovecot is an excellent choice for both small and large installations. It's fast, simple to set up, requires no special administration and it uses very little memory.

How to use this image

To run Dovecot with default configuration simply do:

docker run -d -p 143:143 instrumentisto/dovecot

To see default configuration just run:

docker run --rm instrumentisto/dovecot doveconf

To reconfigure Dovecot add/replace drop-in files in /etc/dovecot/conf.d/ directory inside container, or just specify your own /etc/dovecot/dovecot.conf file:

docker run -d -p 143:143 -v /my/dovecot.cnf:/etc/dovecot/dovecot.conf instrumentisto/dovecot

This image is based on the popular Alpine Linux project, available in the alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
