In the distribution package, 
examples/suggested-minimum-filter-for-windows-clients does the needful 
SA stuff in filter_end(). The mimedefang-filter(5) man page provides all 
the necessary details for how the filter script is structured, including 
functionality not exposed in that example script.

The mimedefang-filter script is simply a Perl script made up primarily 
of subroutines, loaded with a 'require' call from mimedefang.pl. It can 
do ANYTHING that you can write the Perl for it to do.

With that said, it is useful to understand that mimedefang's 
spam_assassin_check() subroutine returns an array in which the third 
item is a comma-delimited string containing the names of all the tests 
that have been matched. So if you're calling spam_assassin_check, you 
already have end results of DKIM and SPF checks.
