Build and Install Yourself¶
Use a release packaged tarball¶
The Cyrus team produce packaged tarballs containing full source and pre-built documentation.

Extract the tarball:
$ tar xzvf cyrus-imapd-x.y.z.tar.gz
These are projects that are not directly developed or managed under the umbrella of the Cyrus Project, but may provide enhancements or additional functionality.
Both of these projects are not under active development, but are definitely worthwhile and would be Good Things to have available. If you think you'd be interested in taking them on and bringing them up to speed, we encourage you to contact the original authors.
There is an effort to develop Cyrus utilities.
Additionally, a Cyrus administrative GUI is available from http://korreio.sf.net
