    Change your MS Outlook (or MS Exchange) settings so it won't send
    winmail.dat files. That file is yet another attempt by Microsoft to
    poison standards... it consists of the message and attachments in normal
    Base64 format unnecessarily encoded a second time with Microsoft's
    proprietary "transport neutral encoding format" (TNEF). Only MS Outlook
    recipients can read it. Many e-mail firewalls strip it because they
    cannot scan the contents for malware.

    Turn it off then Outlook will send messages in normal MIME format which
    can be read by anyone, not just the minority who use MS Outlook.

    To learn how, search for "disable winmail.dat" and you'll find many
    guides, such as this one:
