What is Sisimai

Sisimai is a Perl module for analyzing RFC5322 bounce emails and generating structured data from parsed results. Sisimai is the system formerly known as bounceHammer 4. Sisimai is a coined word: Sisi (the number 4 is pronounced Si in Japanese) and MAI (acronym of Mail Analyzing Interface).

Key features

• Convert Bounce Mails to Structured Data
  • Supported formats are Perl(Hash, Array) and JSON(String)
• Easy to Install, Use.
  • cpan, cpanm, or cpm
  • git clone & make
• High Precision of Analysis
  • 2 times higher than bounceHammer
  • Support 68 MTAs/MDAs/ESPs
  • Support Feedback Loop Message(ARF)
  • Can detect 29 error reasons
• Faster than bounceHammer 2.7.13p3
  • About 2.0 times faster

Command line demo

The following screen shows a demonstration of Sisimai at the command line using Perl(p5-sisimai) and Ruby(rb-sisimai) version of Sisimai.

Usage

Basic usage

Sisimai->make() method provides feature for getting parsed data as Perl Hash reference from bounced email messages like following. Beginning with v4.25.6, new accessor origin which keeps the path to email file as a data source is available.

#! /usr/bin/env perl
use Sisimai;
my $v = Sisimai->make('/path/to/mbox'); # or path to Maildir/

# Beginning with v4.23.0, both make() and dump() method of Sisimai class can
# read bounce messages from variable instead of a path to mailbox
use IO::File;
my $r = '';
my $f = IO::File->new('/path/to/mbox'); # or path to Maildir/
{ local $/ = undef; $r = <$f>; $f->close }
my $v = Sisimai->make(\$r);

# 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);

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/new/1740074341.eml

        my $h = $e->damn();             # Convert to HASH reference
        my $j = $e->dump('json');       # Convert to JSON string
        print $e->dump('json');         # JSON formatted bounce data
    }
}

Convert to JSON

Sisimai->dump() method provides feature for getting parsed data as JSON string from bounced email messages like following.

#! /usr/bin/env perl
use Sisimai;

# Get JSON string from parsed mailbox or Maildir/
my $j = Sisimai->dump('/path/to/mbox'); # or path to Maildir/
                                        # dump() is added in v4.1.27
print $j;                               # parsed data as JSON

# dump() method also accepts "delivered" option like the following code:
my $j = Sisimai->dump('/path/to/mbox', 'delivered' => 1);

Callback feature

Beginning with Sisimai 4.19.0, make() and dump() methods of Sisimai accept a sub routine reference in hook argument for setting a callback method and getting the results generated by the method via Sisimai::Data->catch method.

#! /usr/bin/env perl
use Sisimai;
my $callbackto = sub {
    my $emdata = shift;
    my $caught = { 'x-mailer' => '', 'queue-id' => '' };

    if( $emdata->{'message'} =~ m/^X-Postfix-Queue-ID:\s*(.+)$/m ) {
        $caught->{'queue-id'} = $1;
    }

    $caught->{'x-mailer'} = $emdata->{'headers'}->{'x-mailer'} || '';
    return $caught;
};
my $data = Sisimai->make('/path/to/mbox', 'hook' => $callbackto);
my $json = Sisimai->dump('/path/to/mbox', 'hook' => $callbackto);

print $data->[0]->catch->{'x-mailer'};    # Apple Mail (2.1283)

More information about the callback feature is available at Sisimai | How To Parse - Callback Page.

One-Liner

Beginning with Sisimai 4.1.27, dump() method is available and you can get parsed data as JSON using the method.

$ perl -MSisimai -lE 'print Sisimai->dump(shift)' /path/to/mbox
