You'll want to read up on stream_by_domain() in the mimedefang-filter
man page.  Briefly, in filter_begin() you add a line something like:

  if (stream_by_domain()) { return; }

and then in the other filter_* subroutines you can check $Domain to see
which domain is getting processed.

I've been using it on the hosting server here to provide different
processing for different domains- so far, mostly hand-customized, but
the framework is there to allow user-controlled options.
