Timo,
    Thanks.  The cyrus2dovecot looks to have worked.  So if I understand
the process I now just move the MailDir folder that was created to the
users home directory on our mail server.  I will try the dovecot convert
plugin.  Just make sure I'm doing this correct in the config file:

mail_location = mbox:~/:INBOX=/userM/mail/%u
protocol imap {
  mail_plugins = convert
}
plugin {
  convert_mail = Maildir:~/Maildir:INBOX=/userM/mail/%u
}

Is this correct? The example on the website only shows how to convert
from mbox to MailDir.
