Queue Rights

Hi All,

Can any body tell me wht rights should be granted/should nt be granted
to the privilaged(queue -to- queue) user so that they can not view those
tickets, which actually they are not responsible to resolve?

for e.g :- there are 3 queuse… IT, Finance, HR

A end-user to whom all the queues are visible files a ticket in IT,

a notification mail goes to IT issue resolving team but this ticket
should not be visible to Finance or HR team.
