Thanks for everyones help. So far the testbed is working just fine. The problem I have now is that all of my mail users are using Outlook Express and recieved their email via POP3. I wish to move all of their mail from local storage to the Zimbra server itself..many of them pushing 6g or so.
Is there a tool or utility that will help with this? I have seen the IMAP stuff but they did not use IMAP to the old server. With a few of the users I have created an IMAP connection to the Zimbra server and then recreated the individual folders and copied the mail from one folder to the other but that is exceptionally painful when there is so much data.
