Hi, I have a problem importing mail from Thunderbird to Mail.app on Leopard. I transfered all my messages from windows computer to a mac that ran Tiger OS and Thunderbird. Now a few months later I upgraded OS to Leopard and wish to import messages from Thunderbird to Mail.app. But Mail imports only messages that have been once transfered from windows and doesn't import any of the messages that I have received or sent on my mac these last few months. Could anybody help me with that problem?
