You may want to look at Zarafa combined with Postfix and MySQL. It provides a client to use with Outlook (in a way just like Exchange does), it provides webaccess that looks like OWA/Outlook with working context menus (also in FF), POP, IMAP, etc. http://www.zarafa.com/ There's also a whitepaper about LDAP/AD integration in the website's documentation section. It's NOT free, but I guess it's certainly cheaper than Exchange (I just use the free community version that's limited to 5 users; you could use that to check out if Zarafa suits your needs). -- Rob
