mimedefang.pl - Man Page

Perl script to scan MIME messages.


mimedefang.pl [-f filter] dir


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).


-f filter

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


mimedefang.pl evaluates the file /etc/mail/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/mail/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.
