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__).

![](http://libsisimai.org/static/images/figure/sisimai-overview-1.png)

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 &amp; make
* __High Precision of Analysis__
  * 2 times higher than bounceHammer
  * Support 23 known MTAs and 5 unknown MTAs
  * Support 22 major MSPs(Mail Service Providers)
  * Support  2 major Cloud Email Delivery Services(JSON format)
  * Support Feedback Loop Message(ARF)
  * Can detect 29 error reasons
* __Faster than bounceHammer 2.7.13p3__
  * About 1.7 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-&gt;make()` method provides feature for getting parsed data as Perl Hash reference
from bounced email messages like following.

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

# If you want to get bounce records which reason is "delivered", set "delivered"
# option to make() method like the following:
my $v = Sisimai-&gt;make('/path/to/mbox', 'delivered' =&gt; 1);

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

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

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

Convert to JSON
-------------------------------------------------------------------------------
`Sisimai-&gt;dump()` method provides feature for getting parsed data as JSON string
from bounced email messages like following.

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

# Get JSON string from parsed mailbox or Maildir/
my $j = Sisimai-&gt;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-&gt;dump('/path/to/mbox', 'delivered' =&gt; 1);
```

Read bounce object
-------------------------------------------------------------------------------
The way to read a bounce object retrived from Cloud Email Services as JSON using
their API is the following code. This feature is available at Sisimai 4.20.0 or
later.

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

my $j = JSON-&gt;new;
my $q = '{"json":"string",...}'
my $v = Sisimai-&gt;make($j-&gt;decode($q), 'input' =&gt; 'json');

if( defined $v ) {
    for my $e ( @$v ) { ... }
}
```
As of present, Only Amazon SES and SendGrid are supported.

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-&gt;catch` method.

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

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

    $caught-&gt;{'x-mailer'} = $emdata-&gt;{'headers'}-&gt;{'x-mailer'} || '';
    return $caught;
};
my $list = ['X-Mailer'];
my $data = Sisimai-&gt;make('/path/to/mbox', 'hook' =&gt; $callbackto, 'field' =&gt; $list);
my $json = Sisimai-&gt;dump('/path/to/mbox', 'hook' =&gt; $callbackto, 'field' =&gt; $list);

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

More information about the callback feature is available at
[Sisimai | How To Parse - Callback](http://libsisimai.org/en/usage/#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.

```shell
$ perl -MSisimai -lE 'print Sisimai-&gt;dump(shift)' /path/to/mbox
```

Output example
