NAME

       mimedefang.pl - Perl script to scan MIME messages.

SYNOPSIS

       mimedefang.pl [-f filter] dir

DESCRIPTION

       mimedefang.pl  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 mimedefang(8).

OPTIONS

       -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

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

TESTING FILTERS

       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:

            mimedefang.pl -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.)

MISCELLANEOUS OPTIONS

       There are a few other ways to invoke mimedefang.pl:

            mimedefang.pl -features

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

            SpamAssassin: yes

            mimedefang.pl -validate

       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
       mimedefang.pl exits with an exit code of 1.
