    Well, on a similar note, that type of thing can be done in older versions
    of outlook:

    Pine gives me a line where I can select a file name:
    Attchmnt: 1. /home/blah/test.bat (22 B) "test.txt"

    If I send this to an outlook client, the client refers to the file as
    test.txt everywhere (clicking the paperclip, to open it, and such)...but,
    when I click "Open this" it will actually run the batch file.

    The headers when they show up at oulook are:
    --1363184398-182022148-1008191960=:7769
    Content-Type: TEXT/PLAIN; charset=US-ASCII; name="test.bat"
    Content-Transfer-Encoding: BASE64
    Content-Description: test.txt
    Content-Disposition: attachment; filename="test.bat"

    Now, on a fully patched version of outlook, I can no longer open the
    attachment, but instead get the message:
    Outlook blocked access to the following potentially unsafe attachments:
    test.txt

    (And this also works on .exe files, etc too)
