Subject: WINMAIL.DAT

I noticed that emails from some sources have a file WINMAIL.DAT attached,
or uuencoded, included with the mail message. I can view this file with a
hex editor and it seems to contain a copy of the message, with various
non-ASCII codes between the parts of the message. Those people from whom I
tend to get these WINMAIL.DATs are no experts in email, or computers at
all, and tend to be surprised when I ask them about the attachment. Does
anyone know what is going on on their end? Maybe some Windows mail
software trying to send a formatted version of the text along with the
ASCII text?

Thanks,
     -  Hans

There was already a mail to this list dealing with this subject (Fri, 22 Nov).
I didn't save it, but I just found that I printed it (should be in
comp.mail.pine as a news (Subject: Application/MS-TNEF Enclusures).

"Apparently Microsoft Exchange Mail Clients put attachments in a file called
WINMAIL.DAT. They are in tnef."
