A 100% server side, web-based replacement for the Exchange/Outlook horror combination. Website at http://phpgroupware.org. Supports LDAP, Cyrus/Courier IMAP mailstore or pop3 for the weak-hearted. Multiple sql backends available, including MSSQL. A vast plethora of plugins have been debianised, including but not limited to: a shared mp3 manager, a shared Napster client (to be dropped), WAP support, homepages, IRC, SOAP, RSS....
