I see two options for you: you can accept winmail.dat files with no
scanning at all (see example 1), or you can scan the individual
components of the file (see example 2).
Example 1: (change x to a number suitable number for your setup)
file_list_x_scanner = 0
file_list_x_policy = accept
file_list_x = (?i)(winmail\.dat)$
Use the tnef2multipart.pl script from Advosys to separate and scan the
parts of a winmail.dat archive. See
http://www.advosys.ca/papers/filter-misc/tnef2multipart.pl for the
script and comments on usage. With recent versions of Anomy Sanitizer,
this script can also be found in the contrib directory.
