kohana-mail

Simple mailer for the Kohana framework.

Supports the following senders

mail built-in function
PEAR Mail
PHPMailer
mock sender for testing

It aims to unify mailing system under a single interface so that you can deploy your app independently of available libraries on the server or in your organization.

The SMTP sender for PEAR Mail module uses old PHP4 code that throws strict warnings. If imported, it will automatically disable E_STRICT. It is recommended to use it in PRODUCTION environment and test with an alternate sender.

Basic usage

Mailer::factory()
    ->headers('Content-Type', 'text/html')
    // ->headers('Content-Type', 'text/html; charset=utf-8') to specify UTF-8 character encoding
    ->subject('Hey :username!')
    ->body(View::factory('some_template'))
    ->param(':username', 'John McGuire')
    ->send(array('John McGuire' => 'foo@example.com' ));

The Mail_Sender::param function is used to substitute the body and subject. If you use a View for your body, it is more convenient to pass variables using View::factory.

Headers are set through the headers function. If the value is an array, the header will be parsed as a RFC recipient list.

$mailer->headers('Bcc', array('johndoe@example.com' => 'John Doe'));

Alias are defined for Cc, Bcc, Reply-To and more for convenience.

$mailer->bcc('johndoe@example.com');

Attachments

Attachment content can be appended on a mail using Mail_Sender::attachment. You may specify an array of headers specific to that attachment.

Mail with attachment(s) will be automatically converted to multipart format.

Mailer::factory()
    ->subject('Got a new cat picture for you.')
    ->attachment(file_get_contents('cat.png'), array(
        'Content-Type' => 'image/png',
        'Content-Disposition' => 'attachment; filename=cat.png')
    ->send('foo@example.com');

Receivers

Receivers must comply with the following format:

A simple email

$receiver = "john@example.com"; # a simple email
$receivers = array("john@example.com", "james@example.com"); # a list of emails
$receivers = array("john@example.com" => "John Doe # an associative array
$receivers = array("john@example.com", "james@example.com" => "James Doe"); # a mixed array

It is pretty convenient with the ORM

$receivers = ORM::factory('user')
    ->find_all()
    ->as_array('email', 'full_name');

Mailer::factory()
    ->reply_to('noreply@example.com')
    ->body('Hey guys!')
    ->send($receivers);

Sending heavy mail

You can send heavy mail using register_shutdown_function:

register_shutdown_function(array($mailer, 'send'), $users);

Mail will be sent after the user get his response.

Generating Message-ID

There is a message id implementation based on Matt Curtin & Jamie Zawinski recommendations. It generates secure identifier to make threads and other fancy mailing stuff.

Mailer::factory()
    ->in_reply_to(Mailer::message_id())
    ->body('Hey Foo, long time no see!')
    ->send('foo@example.com')

Testing mail

The module provides a Mock sender to make efficient testing. Mails are pushed in a stack Mail_Sender_Mock::$history so that you can retreive them and test their content.

public function testMail() 
{
    // self-request to send a mail
    Request::factory('send')->execute();

    $mail = array_pop(Mail_Sender_Mock::$history);

    $this->assertEquals('text/html', $mail->headers('Content-Type'));
    $this->assertContains('foo@example.com', $mail->to);

    $this->assertTag(array('tag' => 'a', 'attributes' => array('href' => 'http://example.com')), $mail->body());
}
