The Webmail system is a web-based mail interface for Departmental account holders. Webmail is based on the IMP component of the HORDE project. It features IMAP mail access, easy mail attachment handling, HTML-based messaging, and completely integrated address book/directory service lookup.
Currently Webmail is in the production stages of deployment, and is fully functional. Some features that you like with your current e-mail clients will be added to Webmail as new versions come out. This is an ongoing product with many stages of development ahead.
