[otrs] Keep tickets closed

Hi, I need some help. Im using OTRS and I realized that u can reopen a ticket that was already closed. U can open it by sending a mail or using the client or agent interface. I need to keep the tickets closed for ever. The next state after closed must be closed, I mean none should reopen a ticket. I coudnt find any option using admin privileges, please I need help!!!!!!!!!!!!!!!!! Thanx a lot. _________________________________________________________________ Volvé famosa a tu mascota con MSN http://events.latam.msn.com/tumascota
