mimedefang.pl

MIMEDEFANG.PL(8)					      System Manager's Manual						  MIMEDEFANG.PL(8)

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 -structure < mime_message

       parses a message on stdin and prints lots of debugging information.

	    mimedefang.pl -prettyprint < mime_message

       parses a message on stdin and prints it in a "nice" format (depending on your definition of "nice".)

	    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.
