I am transitioning a company with about 30 IMAP accounts, loaded with data (about 77GB total), to a new email host. The majority of the data will be converted into a local archive and distributed to the company computers as a static reference data set.
The server side folders the users absolutely cannot do without being on the server will be uploaded back to the new server.
I used Mac OS X Mail (Snow Leopard 10.6.6) to download the content. I notice some messages have the name [xxx].partial.emlx, which leads me to believe they have not been downloaded all the way.
I have root access to the mail server data and could download the IMAP server data via FTP. I am not sure what utility to use to convert that data to local Mail.app mailboxes.
Furthermore, I would appreciate any input on the best way to upload a portion of the data to the new server (GoDaddy), preserving the original dates of the messages.

OK - forget the raw server data. I found a script that apparently does pretty good archiving IMAP folders to local mbx files. My main quest now is to batch upload a mailbox hierarchy to the new IMAP server without having to start-stop and deal with similar issues. Anyone know of a utility (hopefully for OS X, but if not, I'll fire up my XP virtual system...) that would be capable of this?
Thanks,
M
