Capturing SMTP Message Id

You can't get the message id using the Laravel Mailer class. Mail::send doesn't return anything special for the drivers.

The SES driver doesn't data anyways: https://github.com/laravel/framework/blob/master/src/Illuminate/Mail/Transport/SesTransport.php#L55

Hi,

Thanks for your reply.

I'm actually not using the SesTransport. I'm using the regular SMTP system of Amazon SES which in turn uses SmtpTransport for SwiftMailer. Is there any way if I can get the underlying instance of SwiftMailer it could return me the Message Id when it sends over to the SMTP?

I know for a fact that Amazon SES via API & SMTP both return a Message Id even though the implementation has not been done in Laravel yet.

Waqas

Actually, You can get Message-ID in Laravel's Mail method:

$message_id = "";
Mail::send('emails.mailTemplate', array(), function ($message) use (&$message_id) {
    $message_id = $message->getId(); // This is the function.
    $message->to('user2@example.com', 'User2')->subject('Checking MessageID');
});
echo $message_id;  // 9910feafbb7fd7ad64c3b8d82627288b@example.com

This is how I solved my problem.

Hi Nirmal,

You are right about the functionality that you have mentioned. But the code snippet that you gave me is returning the SWIFT generated Message Id which is kind of no use to me. I want the Message Id that the SMTP server gives in response when it receives the message and this is I'm sure that my SMTP server is giving a message id in response when it gives the 250 response code right with the code it gives the message id but I've checked the source code for SwiftMailer and Laravel and there's no method I can find that is capturing that message id. If you know of that function that can get me the SMTP Server generated Message Id, that would be very helpful for me.

Thanks for your help.

I am trying to access the "messageID" too that AWS SES returns -- do we have to create a "raw email" instead with code formatted around Amazon's SDK instead to get this messageID?

Thanks!

In case anyone stumbles across this old thread, in the Event Listener suggested by @daylight above,

public function handle($event)
{
      $sesMessageId = $event->message
          ->getHeaders()->get('X-SES-Message-ID')->getValue();
}

Tested: Laravel 8

Just to clarify the Event has to be MessageSent. This can be see in

Illuminate\Mail\Transport\SesTransport

The call is made to SES using the sendRawMail(...) and after that SES sends you the message id which is passed to the MessageSent event.

As a side note I had the same issue where I needed to get the message ID of SES. I used the 'ses' mailer and it worked. Not sure the 'smtp' mailer will work since the only place the 'X-SES-Message-ID' is set is in the SesTransport.php file. Someone with more knowledge can shed some light on this. But the 'ses' mailer does work.

It’s sad that after 10 years, Laravel still doesn’t have any official doc about this.

Here’s how I retrieve the message ID from SES right after sending an email in Laravel 12. I hope this helps someone who encounters the same issue in the future.

$messageId = '';
        	
Event::listen(function (MessageSent $event) use (&$messageId) {
    $messageId = $event->message->getHeaders()->get('X-SES-Message-ID')->getValue();
});

Mail::to('[email protected]')->send(new TestSesMail(htmlString: $html));
