Joseph,

Did you convert the mbox emails to maildir format as well, or just put
dovecot in front of the mbox files and run with the config setting you
described above?  I am attempting to convert all the mbox files to maildir
format for use on a new system, and have found the mb2md.pl script on this
page:

I am going to test the script against a test user and see if it functions
as expected.
