This is dependent on how the outside user sends the mail. I have had this
exact problem many times. In each case where person X was getting winmail.dat
attachments from <foocorp>, while others were getting HTML mail from the same
sender, it has turned out that the sender at <foocorp> had set up mail to
person X differently from the other recipients who were getting HTML mail.

Each time, I have had the sender swear up and down that all recipients were
set up the same way, and then received an apology from the sending site's
mail admin.
