Is the namespace example in the wiki sufficient to enable both mbox and
maildir during a conversion period? I was thinking I would do the large boxes
with one of the other scripts, and turn on the convert plugin for the rest.
Maybe I will have to do some more research. The ideal thing would be if I
could turn on globally new mail in maildir, and convert the existing mail
later. Maybe get the inboxes in /var/spool/mail also done initially. Of course
the users need to be able to access all mail doring the conversion period.

It is only less than 100 users at each site, so less than 200 total users.

I just think it would be more reliable for the backups to not worry if an
inbox is locked during a backup run.
