yii2-mailqueue

Yii2 mail queue component for yii2-swiftmailer.

Limitation

Since 1.1.1 requires PHP >= 7.0

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist tigrov/yii2-mailqueue "~1.1.1"

or add

"tigrov/yii2-mailqueue": "~1.1.1"

to the require section of your composer.json file.

Configuration

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

return [
    // ...
    'components' => [
        'mailer' => [
            'class' => 'tigrov\mailqueue\Mailer',
            'table' => '{{%mail_queue}}',
            'maxAttempts' => 5,
            'attemptIntervals' => [0, 'PT10M', 'PT1H', 'PT6H'],
            'removeFailed' => true,
            'maxPerPeriod' => 10,
            'periodSeconds' => 1,
        ],
    ],
    // ...
];

Following properties are available for customizing the mail queue behavior.

• table name of the database table to store emails added to the queue;
• maxAttempts maximum number of sending attempts per email;
• attemptIntervals seconds or interval specifications to delay between attempts to send a mail message, see http://php.net/manual/en/dateinterval.construct.php;
• removeFailed indicator to remove mail messages which were not sent in maxAttempts;
• maxPerPeriod number of mail messages which could be sent per periodSeconds;
• periodSeconds period in seconds which indicate the time interval for maxPerPeriod option.

Updating database schema

Run yii migrate command in command line:

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

Sending the mail queue

To sending mails from the queue call Yii::$app->mailer->sending() or run the console command yii mailqueue which can be triggered by a CRON job:

* * * * * php /var/www/vhosts/domain.com/yii mailqueue/sending

After the mail message successfully sent it will be deleted from the queue.

Usage

You can then send a mail to the queue as follows:

Yii::$app->mailer->compose('contact/html')
     ->setFrom('[email protected]')
     ->setTo($form->email)
     ->setSubject($form->subject)
     ->setTextBody($form->body)
     ->delay('PT3M') // seconds or an interval specification to delay of sending the mail message, see http://php.net/manual/en/dateinterval.construct.php
     ->unique('unique key') // a unique key for the mail message, new message with the same key will replace the old one
     ->queue();

You can still send mails directly with yii2-swiftmailer:

Yii::$app->mailer->compose('contact/html')
     ->setFrom('[email protected]')
     ->setTo($form->email)
     ->setSubject($form->subject)
     ->setTextBody($form->body)
     ->send();
