after some thought and some trial and errors, I came with this solution.
I don't like it, it look bad.

def main():
    fp = file(folderfile)
    folder = mailbox.UnixMailbox(fp, factory=email.message_from_file)
    while 1:
        mail = email.message_from_file(fp)
        print mail
        if not folder.next():
            break
        #mail = email.message_from_file(fp)

if __name__ == '__main__':
    main()
