NAME

Postfix::ContentFilter - a perl content_filter for postfix

VERSION

Version 1.11

SYNOPSIS

    use Postfix::ContentFilter;

    $exitcode = Postfix::ContentFilter->process(sub{
        $entity = shift; # isa MIME::Entity
        
        # do something with $entity
        
        return $entity;
    });
    
    # Or specifying the parser
    my $cf = Postfix::ContentFilter->new({ parser => 'Mail::Message' });

    $exitcode = $cf->process(sub{
        $entity = shift; # isa Mail::Message
        
        # do something with $entity
        
        return $entity;
    });

    exit $exitcode;

DESCRIPTION

Postfix::ContentFilter can be used for content_filter scripts, as described here: http://www.postfix.org/FILTER_README.html.

FUNCTIONS

new($args) new creates a new Postfix::Contentfilter. It takes an optional argument of a hash with the key 'parser', which specifies the parser to use as per footer. This can be either MIME::Entity or Mail::Message.

Alternatively process can be called directly.

parser($string)

parser() specifies the parser to use, which can be either MIME::Parser or Mail::Message. It defaults to MIME::Parser, if available, or Mail::Message whichever could be found first. When called without any arguments, it returns the current parser.

process($coderef [, $inputhandle])

process() reads the mail from STDIN (or $inputhandle, if given), parses it, calls the coderef and finally runs sendmail with our own command-line arguments (@ARGV).

This function returns the exitcode of sendmail.

VARIABLES

  • $sendmail

    $sendmail defaults to /usr/sbin/sendmail.

        $Postfix::ContentFilter::sendmail = [ '/usr/local/sbin/sendmail', '-G', '-i' ];

    Please note $sendmail must be an arrayref. Don't forget to use the proper arguments for sendmail, or just replace the first element in array.

    Additional arguments can be added with:

        push @$Postfix::ContentFilter::sendmail => '-t';

  • $output

    Any output from sendmail command is populated in $output.

  • $parser

    The MIME::Parser object is available via $parser. To tell where to put the things, use:

        $Postfix::ContentFilter::parser->output_under('/tmp');

CAVEATS

If taint mode is on, %ENV will be stripped:

    delete @ENV{'IFS', 'CDPATH', 'ENV', 'BASH_ENV', 'PATH'}

So set $Postfix::ContentFilter::sendmail to an absolute path, if you are using taint mode. See perlsec(1) for more details about unsafe variables and tainted input.
