NAME - Perl script to scan MIME messages.

SYNOPSIS [-f filter] dir

DESCRIPTION  is  a  Perl  script designed to work with mimedefang(8).  It takes a single
       argument which is a directory  which  should  contain  files  laid  out  as  described  in


       -f filter
              Specifies  the  name of the file containing the filter.  If this option is omitted,
              the default filter /etc/mimedefang-filter is used.

OPERATION evaluates the file /etc/mimedefang-filter as a  Perl  fragment.   This  file
       should  define the filter procedure.  For each part of a MIME message, calls
       filter and disposes of the part as  instructed  by  the  filter.   The  various  modes  of
       disposition are described in mimedefang-filter(5).


       You  are strongly recommended to test your filter before installing it in /etc/mimedefang-
       filter.  To test the filter, save it in a file (e.g. test-filter) and run this command:

   -f test-filter -test

       This tests the filter for syntactic correctness.  If it passes, you can install  it  as  a
       production  filter.   (Note  that  the test tests only for correct Perl syntax; it doesn't
       make sure your filter does something sensible.)


       There are a few other ways to invoke


       prints a list of detected optional Perl modules.  The output looks something like this:

            SpamAssassin: yes


       calls the function filter_validate, if it is  defined  in  your  filter.   filter_validate
       should  return an integer; this becomes the exit code.  If filter_validate does not exist,
       an error message is printed and exits with an exit code of 1.
