If you ever receive a mail with an attachment named "winmail.dat" then
may be disappointed. It is a special format used by Microsoft
Exchange, it contains the files attached to the mail and need some
software to extract them.

Hopefully, there is a little and effecient utility named "tnef" to
extract the files.

Install it: `pkg_add tnef`

List files: `tnef -t winmail.dat`

Extract files: `tnef winmail.dat`

That's all !
