How very timely, I am just this afternoon working on this issue. What I 
have done is removed the "tnef" string from the last line of banned 
attachments in amavisd.conf:
#  qr'^\.(exe|lha|tnef|cab|dll)$',         # banned file(1) types, 
original line
# allow stupid outlook tnef winmail.dat attachments
  qr'^\.(exe|lha|cab|dll)$',         # banned file(1) types

And then restarted amavis.
I am not sure this is proper yet, but I believe it is. On further 
investigation these winmail.dat attachments are tnef encapsulated hooha. 
I also think this should be changed in the default config as many 
outlook/exchange installs seem to be misconfigured in this way.
