[otrs] Tickets created in wrong Queue

Hi , I have setup multiple POP3 accounts , however certain tickets that should go to a certain Queue are in fact created in the wrong queue (I have created a SPAM Queue) , this is puzzling however as I have not setup any SPAM filters on OTRS. OTRS-PM3-10[20615]: [Notice][Kernel::System::Ticket::TicketCreate] New Ticket [200609181069421/no deposit bonu] created (TicketID=349627,Queue=SPAM,Priority=3 normal,State=new) Will PostmasterFilter override any other settings in OTRS?
