I'm setting up a new server with ClearOS 7 Business. I currently have mail for a couple dozen users sitting in mailserver application called MDaemon, on a machine running Windows Server 2008R2. I'm hoping to find info on the best way to get this mail onto my ClearOS machine. The only way I can think of is:
1. Set up each user's account on the ClearOS machine. Have both the new machine and the old machine online, at least on our LAN.
2. Set up a computer somewhere with an email client, and for the first user set it up so the email client is accessing their accounts on both the old and new server. Have the user come into that room, log in to their account on the old machine, and then drag each mail folder from the old account to the new account (yep, you can copy IMAP folders from one account to another, I've done it).
3. When all of the first user's email folders have copied over to the new server, repeat 2. for the next user, until all the mail has been migrated
4. Take the old machine offline and make the new machine accessible from the internet.

Is there a smarter way of doing this, given the difference in platforms?


It turns out, there are applications available specifically for converting MDaemon mailboxes into other formats. Does the IMAP and POP Server software on ClearOS have any sort of import capability? One MDaemon converter can output.the following formats...would any of these benefit me?

PST, MSG, EML, PDF, HTML, RTF, EMLX, MBOX, MBX
