Existing users, 
After completing the mailbox migration, I saw from the dialog box that appeared that I needed to rebuild each migrated mailbox (using the Mail REBUILD menu item). The problem is, there is no way to rebuild multiple mailboxes at once. I have 767 mailboxes total (including mailboxes within Eudora folders of mailboxes). Individually selecting 767 mailboxes and selecting Rebuild from the menu would have taken eons. If there could be found a way around this terrible inconvenience, I might be more excited about the tool.
I have been using Eudora for as long as Eudora has been available (originally from the U of I, Champaign/Urbana). I'm currently using the latest version from Eudora.com and have been fairly happy with it.
I've also been a .Mac member since Apple first launched the service.
I was looking forward to a migration path to Mail so that I might be able to take advantage of some of the features Mail gives me that are unique to Apple...such as .mac syncing.

The disk image has a folder named "Tools". If you look in it, you'll find an applescript which will rebuild all the imported mailboxes so you don't have to manually do it!Monday, April 06 2009 @ 09:25 AM PDT
Use the supplied AppleScript to do this for you... - aamann
The download contains an AppleScript in the "Tools" folder which rebuilds all your imported mailboxes for you - this is mentioned in the Read Me.Reply to This
