I am getting quite a few of these, but they all seem to be really small winmail.dat files i.e. 930B in this case
if I take the file and manually run tnef winmail.dat nothing is extracted, I assume this is the problem, 
in this case they all seem to be Read receipts, would outlook / exchange encupsulate an empty message in a tnef format?

is there a way of getting mailscanner to ignore this?

The problem started when I set the tnef extractor to the internal mailscanner version, when I used /usr/bin/tnef the winmail.dat files where never extracted and placed in the mail content,
