The canonical information on how to use milters in Postfix is in the 
Postfix source tree: README_FILES/MILTER_README.  There's also an HTML 
version.

And I would also second the Dove book Ged links to above, if you are 
about to start fiddling with Postfix configuration.  It's old, but it's 
probably the most complete, and of course, when in doubt look at the 
source, <http://www.postfix.org/> has a lot of resources.
