[otrs] design issue regarding queues / groups and customers

Hello, I have some difficulties to design things the right way when it comes to access policies. I have a basic situation whith two groups of agents (IT and Administration), each has its queue with a "Spam" subqueue. There's a group IT, and a group Administration in order to set the permissions. Now, I want customers to be able to create new tickets from customer.pl, only in queues IT and Administration, so I've set things up so customers belong to both groups : $Self->{CustomerGroupAlwaysGroups} = ['Clients', 'IT', 'Administration']; How should I disable the "Spam" subqueues from the dropdown list when creating a new ticket ?
