Hello people. I have an Ubuntu Server 8.10 setup with postfix and courier-imap. I just built this server as an alternative to Microsoft Exchange which holds the current user accounts with their emails. Is there a way that I can export the emails from Microsoft Exchange for each user and import them into the newly created accounts in postfix?

I must add that I found a way to do this but it is very challenging for my patience. I configured postfix with another domain (user@anotherdomain.com) witch I can configure on each Outlook interface for every user, then copy-paste their emails into the postfix account, then rename the domain after all 25-30 or so accounts are imported. Is there another way for this? There has to be...

Thank you very much and have a nice day
