[otrs] dispatching pb from pop account

Hello, I'm running OTRS 1.2.4 on a SuSE 8.1 and it works great appart from this problem: I've set an external pop account to retrieve tickets, and i cannot make it dispatch to the "To:" field. The mails are stocked into the Raw queue, even if they have the correct "To:" field set as the name of a queue. I've tried with the queue name and the queue name@domain, it just doesn't work. Any help appreciated. --- Bruno
