Yii mailqueue for Yii 2.0 or higher

Email queue component for yii2 that works with yii2-swiftmailer

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist nterms/yii2-mailqueue "*"

or add

"nterms/yii2-mailqueue": "*"

to the require section of your composer.json file.

Configuration

Once the extension is installed, add following code to your application configuration :

return [
    //....
    'components' => [
        'mailqueue' => [
            'class' => 'nterms\mailqueue\MailQueue',
			'table' => '{{%mail_queue}}',
			'mailsPerRound' => 10,
			'maxAttempts' => 3,
        ],
    ],
];

Following properties are available for customizing the mail queue behavior.

table: Name of the database table to store emails added to the queue.
mailsPerRound: Number of emails to send at a time.
maxAttempts: Maximum number of sending attempts per email.

Updating database schema

Apply the database migration to create the table required to store the mail queue messages. To do this, add following code to /config/console.php:

return [
    //....
    'components' => [
        'mailqueue' => [
            'class' => 'nterms\mailqueue\MailQueue',
			'table' => '{{%mail_queue}}',
        ],
    ],
];

then run yii migrate command in command line:

php yii migrate/up --migrationPath=@vendor/nterms/yii2-mailqueue/migrations/

Processing the mail queue

Now calling process() on Yii::$app->mailqueue will process the message queue and send out the emails. In one of your controller actions:

public function actionSend()
{
	Yii::$app->mailqueue->process();
}

Most preferably this could be a console command (eg: mail/send) which can be triggered by a CRON job.

Setting the CRON job

Set a CRON job to run console command:


*/10 * * * * php /var/www/html/myapp/yii mailqueue/process

Usage

You can then send an email to the queue as follows:

Yii::$app->mailqueue->compose('contact/html')
     ->setFrom('from@domain.com')
     ->setTo($form->email)
     ->setSubject($form->subject)
     ->setTextBody($form->body)
     ->queue();

While nterms\mailqueue\MailQueue extends from yii\swiftmailer\Mailer, you can replace it with this extension by adding yii2-swiftmailer configuations directly to mailqueue configurations as follows:

return [
    //....
    'components' => [
        'mailqueue' => [
            'class' => 'nterms\mailqueue\MailQueue',
			'table' => '{{%mail_queue}}',
			'mailsPerRound' => 10,
			'maxAttempts' => 3,
			'transport' => [
				'class' => 'Swift_SmtpTransport',
				'host' => 'localhost',
				'username' => 'username',
				'password' => 'password',
				'port' => '587',
				'encryption' => 'tls',
			],
        ],
    ],
];

And use following code for directly sending emails as you ususally do with yii2-swiftmailer:

Yii::$app->mailqueue->compose('contact/html')
     ->setFrom('from@domain.com')
     ->setTo($form->email)
     ->setSubject($form->subject)
     ->setTextBody($form->body)
     ->send();
