use Sisimai::Message;

my $mailbox = Sisimai::Mail->new('/var/mail/root');
while( my $r = $mailbox->read ) {
    my $p = Sisimai::Message->new('data' => $r, 'input' => 'email');
}

my $notmail = '/home/neko/Maildir/cur/22222';   # is not a bounce email
my $mailobj = Sisimai::Mail->new($notmail);

DESCRIPTION

Sisimai::Message::Email convert bounce email text to data structure. It resolve email text into an UNIX From line, the header part of the mail, delivery status, and RFC822 header part. When the email given as a argument of "new()" method is not a bounce email, the method returns "undef".

CLASS METHODS

new(Hash reference)

new() is a constructor of Sisimai::Message

my $mailtxt = 'Entire email text';
my $message = Sisimai::Message->new('data' => $mailtxt);

If you have implemented a custom MTA module and use it, set the value of "load" in the argument of this method as an array reference like following code:

my $message = Sisimai::Message->new(
                    'data' => $mailtxt,
                    'load' => ['Your::Custom::MTA::Module']
              );

Beginning from v4.19.0, `hook` argument is available to callback user defined method like the following codes:

my $cmethod = sub {
    my $argv = shift;
    my $data = {
        'queue-id' => '',
        'x-mailer' => '',
        'precedence' => '',
    };

    # Header part of the bounced mail
    for my $e ( 'x-mailer', 'precedence' ) {
        next unless exists $argv->{'headers'}->{ $e };
        $data->{ $e } = $argv->{'headers'}->{ $e };
    }

    # Message body of the bounced email
    if( $argv->{'message'} =~ /^X-Postfix-Queue-ID:\s*(.+)$/m ) {
        $data->{'queue-id'} = $1;
    }

    return $data;
};

my $message = Sisimai::Message->new(
    'data' => $mailtxt, 
    'hook' => $cmethod,
    'field' => ['X-Mailer', 'Precedence']
);
print $message->catch->{'x-mailer'};    # Apple Mail (2.1283)
print $message->catch->{'queue-id'};    # 2DAEB222022E
print $message->catch->{'precedence'};  # bulk
