AfterMailerInitializationEvent

Example

An example listener, which hooks into the Mailer API to modify mailer settings to not send any emails ("null mailer"), could look like this:

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Mail\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\Mail\Event\AfterMailerInitializationEvent;

#[AsEventListener(
    identifier: 'my-extension/after-mailer-initialization',
)]
final readonly class MyEventListener
{
    public function __invoke(AfterMailerInitializationEvent $event): void
    {
        $event->getMailer()->injectMailSettings(['transport' => 'null']);
    }
}

API

class AfterMailerInitializationEvent

Fully qualified name

\TYPO3\CMS\Core\Mail\Event\AfterMailerInitializationEvent

This event is fired once a new Mailer is instantiated with specific transport settings.

So it is possible to add custom mailing settings.

getMailer ( )

Returns

\Symfony\Component\Mailer\MailerInterface
