*Some* winmail.dat attachments cannot be decoded and scanned. There is an
option near the bottom of the mailscanner.conf configuration file to enable
you to deliver these anyway. There are no better TNEF decoders in existence

I have tried to get the file format spec out of Microsoft, but to no avail :-(
