Are there any good maildir manipulation utilities out there?

Yes, on digging a bit further into this using mairix isn't too
difficult:-

    Search with mairix producing a maildir full of symbolic links to
    the hits.

    Move the *target* of the symbolic links to the new directory as
    required.

    Delete the target of the symbolic links.

Job done!  Since there are already readlink and/or readpath commands
for finding the target of a symbolic link this is rather easy.
