Some mail programs allow you to import messages from a text file. Therefore, you could use the following method:

    1. download a notebook log
    2. save it to two files: a backup file and a file that you edit
    3. edit with a plain ascii editor that can handle large files and save it locally
    4. import the edited file into your e-mail message

Of course, your mail program must allow you to create very large messages. It may be necessary for you to either update the release level of your current mail program, if possible, or obtain another program.
