[otrs] Two tickets for same mail problem

Hi all, I m facing a peculiar problem. When the customer sends a mail to both foo@xyz.com and bar@xyz.com. And both these emails are configured as POP3 accounts in OTRS, attached to respective queues. Then OTRS creates two duplicate tickets, one from foo@xyz.com and other from bar@xyz.com, into their respective queues. Is this rite? How can we overcome this behaviour? Or rather what should agent do in such situation while replying to such duplicate tickets. Thanks. Bring your gang together. Do your thing.
