[bincimap] still getting this error

[Jeremy Hansen]

I still don't understand what this error means:

ERROR : Could not complete request.
Query: CREATE "INBOX.Sent"
Reason Given: CREATE failed: With a Maildir++ depot, you must create all 
mailboxes under INBOX. Try creating INBOX/INBOX.Sent.

I turn off courier and turn on binc and this is what I get.

My directory stucture is

$HOME/Maildir/{new,cur,tmp,.Sent}

for virtual users it's

$HOME/users/<virtualpop>/{new,cur,tmp,.Sent}

What exactly should I do here.  I'm confused.

Thanks
