We have following issue: After upgrade from 2.1 to 2.2.13 clients can
create folders with names containing slash character.
This was not possible with our previous version 2.1. Tested.
Our Dovecot runs on Debian Wheezy system. According
http://wiki2.dovecot.org/Plugins/Listescape this should be disabled on
a Posix system.
We use the usual separator '.' as you can see in the config file later.
Issue can be reproduced using outlook 2013.
On the file system this is the representation of the "Family/Friends"
folder
/home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends
/home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/new
/home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/tmp
/home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/cur
Doveadm does not lists properly the folder
doveadm mailbox list -ust...@alltimes.com |grep -i Family
INBOX.Family
This is the server configuration:

-----------------------
We need a way to prevent creation of those folders, because our users
create several of them a day. Any suggestions?
