Laravel 9 SymfonyMailer error - An email must have a "To", "Cc", or "Bcc" header

Question

I've got problems with sending emails after updating a Laravel 8 project using the Metronic 8 theme to Laravel 9. I didn't change any of my code related to emails, but now I got this error using the Sendmail driver :

An email must have a "To", "Cc", or "Bcc" header. {"userId":6,"exception":"[object] (Symfony\Component\Mime\Exception\LogicException(code: 0): An email must have a "To", "Cc", or "Bcc" header. at /home/myhome/public_html/myproject.com/vendor/symfony/mime/Message.php:128)

Controller

class MyController extends Controller
{
    public function activate($id)
    {
        $mymodel = MyModel::find($id);

        $contact = Contact::where('mymodel_id', $mymodel->id)->first();
        Mail::to($contact->email)->send(new MyMail($contact));
    }
}

Mailable

class MailActive extends Mailable
{
    use Queueable, SerializesModels;

    protected $contact;

    public function __construct(Contact $contact)
    {
        $this->contact = $contact;
    }

    public function build()
    {
        return $this->from('theemail@gmail.com', 'Me')
            ->view('emails.myemailview')
            ->with([
                'contact' => $this->contact
            ]);

        // $this->withSymfonyMessage(function (Email $message) {
        //     $message->getHeaders()->addTextHeader(
        //         'addAddress', 'theemail@gmail.com'
        //     );
        // });

        // return $this;
    }
}

I've tried to render the mail alone, and it works. Using the log driver, it works, and as you can see, I even tried to bypass the Mail facade using the withSymfonyMessage method in the mailable class, but nothing works.

Is there a config or a part I'm missing? Could I go back using SwiftMailer without much trouble for Laravel 9 to work?

In your upgrade process can you install these packages? `composer require symfony/mailgun-mailer symfony/http-client` — Jinal Somaiya, Feb 17 '22 at 11:16
What have you tried to resolve the problem? As far as I see, you are not setting any receiver in the given code? — Nico Haase, Feb 17 '22 at 15:10

use ->to()

return $this->from('theemail@gmail.com', 'Me')
            ->to($email, $name)
            ->view('emails.myemailview')
            ->with([
                'contact' => $this->contact
            ]);

It works like that yes ! The Mail facade doesn't take the to() anymore and we have to specify the address in the Mailable class ? – Ankh Feb 17 '22 at 12:47
I am using Laravel 10. where to include this snippet ? I don't have any `build()` – mr-possible May 11 '23 at 16:29

An email must have a "To", "Cc", or "Bcc" header. {"userId":6,"exception":"[object] (Symfony\Component\Mime\Exception\LogicException(code: 0): An email must have a "To", "Cc", or "Bcc" header. at /home/myhome/public_html/myproject.com/vendor/symfony/mime/Message.php:128)

You will get the above exception if to() is missing or if the to() method receive an empty collection in your Mailable class

I am using Laravel 10+ and doing just this while calling Mail facade, worked for me:

\Mail::to('to@example.com')->send(new MyMailableClass());

P.S. I am using MailTrap to test my emails for this.

Hope it helps!

Please add some explanation to your answer such that others can learn from it. Shouldn't the mail be sent to a varying mail address instead of a static one? – Nico Haase Aug 14 '23 at 07:36
