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

Hopefully, there is a simple 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!
