migrate mail from Ms Exchange to Linux
I need to migrate mail from an exchange server to linux mailserver running a courier-imap mail store.
My current approach will be to use to
1. Dump the username and passwords from Active directory on the Ms exchange server into an LDIF file
2. Install a postfix, courier-imap, ldap mailserver
However i am not too sure on how to move users mail from the exchange server to the new imap mailboxes
I have searched for similar posts but most have been unanswered.
