NAME

Sisimai - Mail Analyzing Interface for bounce mails.

SYNOPSIS

    use Sisimai;

DESCRIPTION

Sisimai is a Mail Analyzing Interface for email bounce, is a Perl module to parse RFC5322 bounce mails and generating structured data as JSON from parsed results. 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')

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/
    #  $v = Sisimai->make(\'From Mailer-Daemon ...');

    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
            print $e->origin;               # /var/spool/bounce/2022-2222.eml

            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')

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,
    );
    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'
    }

match()

match method receives an error message as a string and returns a reason name like the following:

    use Sisimai;
    my $v = '550 5.1.1 User unknown';
    my $r = Sisimai->match($v);
