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.
