Status Report: Chandler Desktop and Server - page 3
Where Things Stand
To send and receive e-mail you'll need to configure Chandler with the appropriate server addresses and login information. Chandler is not meant to be your primary e-mail client with this release. It is expected that you'll want to move some information between e-mail and Chandler. This is best done using IMAP folders. The Chandler Wiki has complete instructions on how to set up the proper folders on your mail server to make this easy.
Another aspect of the Chandler project is a server to facilitate collaboration between a small group or team. This collaboration consists of sharing project information in the form of schedules and tasks. It also makes it easy to see everyone's calendar and schedule meetings based on an individual's availability. The Chandler Hub server installs on either a local server or you can use the OSAF's public Chandler Hub.
If you're using a local installation of Cosmo, you'll have a few options to consider. The basic installation of Cosmo comes with the Derby embedded database. Instructions for configuring Cosmo to use MySQL are provided on the Chandler Project website. There are also a number of options when it comes to the Java Virtual Machine (JVM). You'll find tips and hints for configuring your JVM for heavy usage on the same web site along with recommendations on which JVM to use (hint: it isn't the default Sun JVM).
