Laravel: Get bad_domains from Mailable - php

Question

I am sending mails with Laravel like this:
foreach ($users as $user) {
\Mail::to($user())->send(new Newsletter($user));
}
I would like to have an array of all the users who had a bad_domain response. I found in the docs that Laravel uses Swiftmailer which has a way to find bad_domain respones:
// Pass a variable name to the send() method
if (!$mailer->send($message, $failures))
{
echo "Failures:";
print_r($failures);
}
/*
Failures:
Array (
0 => receiver#bad-domain.org,
1 => other-receiver#bad-domain.org
)
*/
However, I want to use the a Mailable class. I am not sure how I can do this with the Swiftmailer (which I can access through \Mail::getSwiftMailer()).
Is there any easy way of getting the bad_domains when using Mailable from Laravel?

You may only access bad_domains, but not bounces with Swiftmailer (Swiftmailer 4 does not retrieve bounces as $failedRecipients).
One can get bad_domains it with
\Mail::to($user)->send(new \App\Mail\Hi());
dd(\Mail::failures());
See Illuminate\Mail\Mailer.php
/**
* Send a Swift Message instance.
*
* #param \Swift_Message $message
* #return void
*/
protected function sendSwiftMessage($message)
{
try {
return $this->swift->send($message, $this->failedRecipients);
} finally {
$this->forceReconnection();
}
}
