Kalau tanpa attachment maka effect TNEF tidak terlihat, tidak ada
winmail.dat.

Kalau tautan yang diberikan dibaca

What is RTF, TNEF and winmail.dat?

Outlook can use a special method, technically referred to as Transport
Neutral Encapsulation Format (TNEF), to package information for sending
messages. The use of TNEF is affected by settings in Outlook that are
referred to as Rich Text Format (RTF). TNEF and RTF are not identical,
but they are very similar.

A TNEF-encoded message contains a plain text version of the message and
a binary attachment that "packages" various other parts of the original
message. In most cases, the binary attachment is named Winmail.dat, and
it includes the following information (if included in the message):

    The formatted text version of the message (ie, font and colors).
    OLE objects (such as embedded pictures and embedded Office documents).
    Special Outlook features (i.e., custom forms, voting buttons, and
meeting requests).
    Regular file attachments that were attached to the original message.

Header ini artinya adalah message pakai format MS-TNEF

Sender [email protected] menggunakan office outlook 2016 yang ada bug
untuk MS-TNEF sehingga sekalipun sudah menset recipient address tidak
pakai RTF di daftar contactnya tetapi akan tetap terpicu pakai format RTF.
Bug itu hanya bisa diperbaiki setelah melakukan patch update.

Update ke MD 18.0.1 tidak akan membuat worldclient webmail jadi bisa
decode (baca) winmail.dat, tetapi memperbaiki MDAV agar tidak
mengkarantina message dengan winmail.dat attachment.
