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

Exchange --> Postfix
Hello, I want to _change_ MsExchange to Postfix in my corporation. I have 150 users in my network. They work in Outlook 2003. We are using Active Directory to authentification. Could you tell me what is the consequencies of making that change. Especialy I would like to know: 1. Is Postfix cooperate with Active Directory or eDirectory? Anybody use Postfix with AD or eDirectory? 2. I know that communication between Exchange and Outlook is with MAPI protocol. Does Postfix use the MAPI protocol? 3. If 2 is no, Is Postfix POP or IMAP server? I would like to use POP or IMAP protocol instead MAPI. 4. Is this possible that Postfix has a "Outlook calendar" feature and other "Outlook like feature". 5. Does Postfix support TLS, SSL? 6. Does Postfix support acces via http to mail box? Thanks pch0317
