PHPMailer 6 was released with some breaking backwards compatibility changes and minimum requirement of php 5.5.

This package does not yet supports PHPMailer 6 (work on its support is in progress, but there is no due date at the moment).

This extension adds integration of popular PHPMailer library - a "full-featured email creation and transfer class for PHP" - to Yii 2 framework.

Although extension classes implement yii\mail\MailerInterface and yii\mail\MessageInterface, some methods of Yii 2 BaseMailer and BaseMessage are overriden - mainly because of PHPMailer-specific issues.

Nevertheless - the behavior of the extension should remain expected and predictable and comply interfaces mentioned above (I believe so). If not - feel free to report issues.


You should generally follow Yii 2 requirements. The minimum is that your Web server supports PHP 5.4.0.


Install via Composer

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

During the extension installation PHPMailer library will be also installed (if not already present in your prject).

So, either run

php composer.phar require --prefer-dist zyx/zyx-phpmailer "^0.9.4"

or add respectively:

"zyx/zyx-phpmailer": "^0.9.4"

to the require section of your composer.json.

Note: this can be affected by 'minimum-stability' settings in your project root composer.json file. If you want to install version with stability other than 'minimum-stability' of your project, you should explicitly point to it in the require section of composer.json in your project root.

Install from an Archive File

You may install extension manually. For that purpose you have to download archive file and extract it into vendor/zyx directory of your project.

You'll also need to download PHPMailer library and extract it to vendor/phpmailer directory of your project.

Note: due to naming agreement 3rd-party extensions and libraries are kept under vendor directory.

One of the benefits of installing via Composer is automation of autoload setup. If you install extension and PHPMailer library from archive files, you'll have to setup autoload paths manually.

Note: currently PHPMailer does not support namespaces (as its minimum requirements is php 5.0), but provides an SPL-compatible autoloader, and...

the preferred way of loading the library - just require '/path/to/PHPMailerAutoload.php'; and everything should work

For further information refer to PHPMailer documentation.


To use this extension, you should add some settings in your application configuration file. It may be like the following:

return [
	'components' => [
        'mailer' => [
            'class'            => 'zyx\phpmailer\Mailer',
            'viewPath'         => '@common/mail',
            'useFileTransport' => false,
            'config'           => [
                'mailer'     => 'smtp',
                'host'       => 'smtp.yandex.ru',
                'port'       => '465',
                'smtpsecure' => 'ssl',
                'smtpauth'   => true,
                'username'   => 'mysmtplogin@example.ru',
                'password'   => 'mYsmTpPassword',

This is the tipical configuration for sending email via yandex smtp.

If you are familiar with PHPMailer, you can see that 'config' array holds settings, similar to corresponding PHPMailer properties. They will be populated when Mailer is initialized.

You can for example define

'mailer' => 'mail' or

'mailer' => 'sendmail', 'sendmail' => '/path/to/sendmail' - just like in PHPMailer.

You may also configure some default message settings for your application in 'messageConfig' array. They will be populated at the moment of message creation.

For example, you may predefine default contents of 'From' email field - so you will not have to set 'From' it every time when composing message:

    'mailer' => [
        'messageConfig'    => [
         'from' => ['noreply@example.com' => 'My Example Site']


Example of simple usage:

     ->setFrom(['noreply@example.com' => 'My Example Site'])
     ->setTo([$form->email => $form->name])

Example of sending html emails rendering view and layout (assumed that default 'From' is set in application configuration file):

Yii::$app->mailer->compose('passwordResetToken', ['user'       => $user,
                                                'title'      => Yii::t('app', 'Password reset'),
                                                'htmlLayout' => 'layouts/html-reset'])
                ->setSubject(Yii::t('app', 'Password reset for ') . Yii::$app->params['siteName'])

Note: possibility to set 'htmlLayout' dynamically when composing message is not the native behavior of BaseMailer. This feature was introduced in this specific extension and is experimental.

For more examples of usage you may refer to documentation on Yii 2 BaseMailer and BaseMessage and PHPDoc blocks in the extension files.

Additionally some Wiki articles are available.
