message redelivers itself over again from same sender

One of my end users received a message from outside with a 24MB file and now it redelivers back to the inbox several times with the attachment.  He called his sender and he said he only sent it only one time but keeps appearing over and over again.  I am running Exchange 2000 Server and the sender is running the same Server as well.  Why is this happenning?

    One of the server's doesn't think that the message has been delivered correctly, and is resending it.
    A common cause of that problem is a firewall interfering with the traffic. The PIX is notorious for this.

    Have you looked at the message to see if they are identical? You will need to look for the message ID in the header information within Outlook.

    I do have a PIX firewall and had a problem with Exchange redelivering a particular message to a group of clients every night at about midnight until I finally killed it from the queue. Can you tell me more about this notorious PIX problem or direct me to somewhere where it is documented?
