I think I will have to stay with the 1.x branch since we have to stick to using approved rpm's (internal policy) and fedora 13 does not have a 2.x branch that I see yet. So maildir it is for now.
I see my error on the inbox not getting the new mail. That was one of those "all nighter" errors that I just plain missed due to lack of sleep. I forgot to point postfix to the proper place to deliver the mail.
So once I setup postfix to deliver the mail properly and the dovecot convert plugin is setup, is there a way to gradually migrate the users so I don't kill the server? We have about 220GB or so of mail between about 160+/- users. What would be the best way to migrate it all to maildir?

Is there a repo out there that I can install 2.0 from? The only one I have found is atrpms and it is a pain to get conflict worked out with other packages.
If you use Dovecot 2.0 you also get the choice of multi-dbox.
http://wiki2.dovecot.org/MailboxFormat/dbox
This would give you some advantages:
With multi-dbox, multiple messages are stored in the same file. But once a mail file contains 2 megabytes (configurable), Dovecot moves on to a new file and leaves the old files unchanging. This should be quite nice for your backup strategy because you would only backup the "current" file for each user, limited to 2 megabytes per user (or whatever amount you think appropriate).
With multi-dbox, if you have many small messages, these are all stored in the same file. This vastly reduces the number of files required to store mail, which means fewer inodes consumed, and I think backup systems often work better with a smaller number of larger files than a larger number of smaller files.
If you use multi-dbox, you will need to use a Dovecot delivery software (e.g. dovecot-lda).
