moving messages between namespaces go into purge

[justina colmena ~biz]

Mails stored as individual files in a "Maildir/" can conceivably be "moved" 
within the O/S file system rather than copied, but the default flatfile 
Mailbox format does require a copy-and-purge, as far as I know.

/etc/postfix/main.cf:
    # DELIVERY TO MAILBOX
    #
    # The home_mailbox parameter specifies the optional pathname of a
    # mailbox file relative to a user's home directory. The default
    # mailbox file is /var/spool/mail/user or /var/mail/user.  Specify
    # "Maildir/" for qmail-style delivery (the / is required).
    #
    #home_mailbox = Mailbox
    home_mailbox = Maildir/
