dovecot - Jan 2004 - Migrating from UW: mbx detection and conversion

I want to migrate my big mail folder hierarchy in preparation for converting
from UW-IMAP to Dovecot. I've got a bunch of mbx format folders but some
remain mbox. Has anyone done this? Any scripts out there for automating the
conversion to all-mbox?

I believe the only format conversion available is mailutil (part of UW-IMAP)
and it works by opening an IMAP connection to the server and moving messages
from one folder to the other. Is there any simpler method?

I'm using the script from

BTW, I discovered that "file" on Fedora understands mbx format, so the
following one-liner will find all the mbx files in a hierarchy:

 file `find . -type f` | grep MBX
