If they are both duplicated, then the message duplication is in the transport path somewhere, often in the path between your mail server and your computer, or even inside your computer. If the Date is the same but the Message-ID is hideously different (they look unrelated), the duplication is probably inside your ISP. If the Date fields differ and the Message-ID field is the same, the problem is in the software in the sender's computer. If the Date and Message-ID fields both differ between duplicated copies of the message, then they are in all probability being sent more than once by the sender. The most common cause of message duplication is an ISP running out of disk space on their mail computer. The mail is delivered to your ISP but its disk fills up, and the sending ISP has no way of knowing whether the message got through before the disk filled up, so the sending ISP's computer does not mark the message as "delivered", and tries again to deliver it half an hour later.
