    I have a question about multipart/signed message handling in Vista's
    Windows Mail application pursuant to RFC 1847 section 2.1. When Windows
    Mail receives a message in multipart/signed format with just the 2 body
    parts specified in the RFC, Windows Mail does not display the body text
    in the message and instead puts the entire body into a text file that
    appears to be named ATT#####.txt where the #'s are numbers, such as
    00013. However, when I alter the message so that inside the
    multipart/signed message is multipart/alternative nested MIME
    formatting, Windows Mail does correctly display the HTML version of the

    I have several questions:

    Why does Windows Mail not correctly display the message body when a
    standard multipart/signed MIME format is used? (The message is instead
    displayed as a .txt attachment with a blank message body.)

    Why does it display correctly when another multipart/alternative MIME
    body appears beneath the multipart/signed body? (In this case the HTML
    alternative message body is displayed as expected.)

    Is there any way to get Windows Mail to display the body correctly when
    only the multipart/signed MIME formatting is used?

  2. I don't think you can fix it. Its probably a bug. You can try saving the
    message and then renaming it to give it a mht file extension and then it
    will open in IE. I don't know what the result will be.

    10 years ago.:mad:
