NAME

Sisimai - Mail Analyzing Interface for bounce mails.

SYNOPSIS

use Sisimai;

DESCRIPTION

Sisimai is the system formerly known as bounceHammer 4, is a Perl module for analyzing bounce mails and generate structured data in a JSON format (YAML is also available if "YAML" module is installed on your system) from parsed bounce messages. Sisimai is a coined word: Sisi (the number 4 is pronounced "Si" in Japanese) and MAI (acronym of "Mail Analyzing Interface").

BASIC USAGE

make('/path/to/mbox', delivered = 1)>

make method provides feature for getting parsed data from bounced email messages like following.

use Sisimai;
my $v = Sisimai->make('/path/to/mbox'); # or Path to Maildir

if( defined $v ) {
    for my $e ( @$v ) {
        print ref $e;                   # Sisimai::Data
        print ref $e->recipient;        # Sisimai::Address
        print ref $e->timestamp;        # Sisimai::Time

        print $e->addresser->address;   # shironeko@example.org # From
        print $e->recipient->address;   # kijitora@example.jp   # To
        print $e->recipient->host;      # example.jp
        print $e->deliverystatus;       # 5.1.1
        print $e->replycode;            # 550
        print $e->reason;               # userunknown

        my $h = $e->damn;               # Convert to HASH reference
        my $j = $e->dump('json');       # Convert to JSON string
        my $y = $e->dump('yaml');       # Convert to YAML string
    }

    # Dump entire list as a JSON 
    use JSON '-convert_blessed_universally';
    my $json = JSON->new->allow_blessed->convert_blessed;

    printf "%s\n", $json->encode($v);
}

If you want to get bounce records which reason is "delivered", set "delivered" option to make() method like the following:

my $v = Sisimai->make('/path/to/mbox', 'delivered' => 1);

dump('/path/to/mbox', delivered = 1)>

dump method provides feature to get parsed data from bounced email as JSON.

use Sisimai;
my $v = Sisimai->dump('/path/to/mbox'); # or Path to Maildir
print $v;                               # JSON string

OTHER WAYS TO PARSE

Read email data from STDIN

If you want to pass email data from STDIN, specify STDIN at the first argument of dump() and make() method like following command:

% cat ./path/to/bounce.eml | perl -MSisimai -lE 'print Sisimai->dump(STDIN)'

Callback Feature

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

OTHER METHODS

engine()

engine method provides table including parser engine list and it's description.

use Sisimai;
my $v = Sisimai->engine();
for my $e ( keys %$v ) {
    print $e;           # Sisimai::MTA::Sendmail
    print $v->{ $e };   # V8Sendmail: /usr/sbin/sendmail
}

reason()

reason method provides table including all the reasons Sisimai can detect

use Sisimai;
my $v = Sisimai->reason();
for my $e ( keys %$v ) {
    print $e;           # Blocked
    print $v->{ $e };   # 'Email rejected due to client IP address or a hostname'
}
