[Dovecot] Migrating from uw-imapd to dovecot

[Chris Wakelin]

Do you mean some folders are in the UW-IMAP proprietary "mbx" format
(essentially an mbox with extra indexing information included)? If so,
you'll need to convert them to plain "mbox" files, using something like
UW-IMAPs "mailutil" command:

mailutil copy <rooted unix path to folder> "#driver.unix:<rooted unix
path to new folder>#'

e.g. mailutil copy `pwd`/mbx-folder "#driver.unix:`pwd`/mbox-folder"

then rename/delete the original folder and move the new one to replace it.

Hope this helps,
Chris
