We are trying to use OTRS to manage multiple company's tickets. However, there doesn't seem to be a way to automatically associate 'customers' with queues when they create customer accounts. The ideal case would be to use the domain part of the email address to make a decision for what queue they can see. This feature exists when people submit tickets via email; I am able to route their ticket to their company's queue. The best I can figure out is to not allow newly registered users to submit tickets at all through the web interface until an admin assigns them a group. This would work fine except I can't alert the admin that a new customer has been registered.
