[imp] IMP+COURIER Invalid mailbox name

[Supporto Tecnico Dinosoft]

Good morning 
i'm using IMP H3 (4.0.4-RC1) with Courier-IMAP
my server.php is

$servers['imap'] = array(
	'name' => 'Courier IMAP',
	'server' => 'localhost',
	'hordeauth' => false,
	'protocol' => 'imap/notls',
	'port' => 143,
	'folders' => '',
	'namespace' => 'INBOX.',
	'maildomain' => 'dinosoft.it',
	'smtphost' => 'localhost',
	'smtpport' => 25,
	'realm' =>'',
	'preferred =>'',
	'dotfiles =>false,
	'hierarchies' => array()
);


Every time i try to create a folder or send an email by IMP i
receive 

i.e Cannot create Sent folder : invalid mailbox name.

Why This

My courierimapsubscribed is
INBOX.Sent
INBOX.Trash
INBOX.Drafts

MY COURIER mailbox tree is  with this type.
If i have an email support at dinosoft.it the tree is

support/.maildir/.Drafts
support/.maildir/.Sent
support/.maildir/.Trash.

and so on....

Any help ? Befeore IMP we use Squirrelmail and we have no problem
What are our mistakes ???

Thanks Dinosoft Staff
