    TNEF encoding

    Hi All,

    I'm currently porting a VC++ app that generates SMTP messages to C#. Part
    of the generate message header is a TNEF stream that enables a custom form
    to be used when that email is received by an Exchange server.

    I'm using the System.Web.Mail classes to generate my C# SMTP message. Can
    someone point me in the right direction for adding a TNEF stream to a
    message of this type.

    From what I've found so far, it looks like I need to generate a winmail.dat
    attachment which is base64 encoded, but what goes into the attachment?

    TIA
    Chris
