BUG: cannot move messages to root mailfolder in namespace "There can be only one namespace with inbox=yes"

[Martin Johannes Dauser]

Hi,

"The section name in namespaces (e.g. namespace sectionname { .. } is
used only internally within configuration. It's not required at all,
but it allows you to update an existing namespace 
(like how 15-mailboxes.conf does) or have userdb override namespace
settings for specific users (namespace/sectionname/prefix=foo/)." 
(from https://wiki.dovecot.org/Namespaces)

You can call the namespace as you wish or leave it out, but it's a nice
hint telling it's purpose and if you activate debug level it's easier
to see which namespace does what.

There is no alphabetical order taken in account.

Regarding duplicate prefix: I didn't thought of that. Using prefix
Archive/ should lead to a mailbox /Archive/Archive I guess. I'm not
sure if namespace attribute "list = no" could do something about it.

Another way round would be to set the prefix of inbox as Inbox/ instead
but this would force users to create folders only as subfolders of
/INBOX/ or of /Archive/.

I'm glad I could be of some help.
Martin
