Email Notification Issues

We've recently started experiencing issues with the notifications being sent from our application, having made no major changes to the environment. We had been using mailgun to send notifications, but have changed to using SES hoping it would solve it.

This is the error:

Symfony\Component\Mailer\Exception\HttpTransportException Unable to send an email: to parameter is missing (code 400)

This is happening on all notifications which had all previously worked without issue. The only thing I've found relating to it is this github issue, but it's not helped me figure it out. The suggestion of changing the http version didn't work.

https://github.com/symfony/symfony/issues/45548

Has anyone on here experienced the same and found a solution?

It seems like the issue you're encountering is related to the to parameter not being set or recognized when sending an email. This could be due to a misconfiguration in your code or a problem with the integration between your application and the email service (in this case, SES).

Here's a checklist to troubleshoot and potentially solve the issue:

  1. Check Configuration: Ensure that your mail configuration in config/mail.php is set up correctly for SES. It should look something like this:
// config/mail.php

return [
    // ...

    'mailers' => [
        'ses' => [
            'transport' => 'ses',
        ],
        // ...
    ],

    // ...
];
  1. Check Environment Variables: Make sure that your .env file has the correct SES credentials and that they are being loaded properly.
MAIL_MAILER=ses
AWS_ACCESS_KEY_ID=your-access-key-id
AWS_SECRET_ACCESS_KEY=your-secret-access-key
AWS_DEFAULT_REGION=your-region-1
  1. Update Dependencies: If there's a bug in the version of the Symfony Mailer or Laravel framework you're using, updating to the latest stable version might solve the issue.
composer update
  1. Inspect Notification Code: Review the code where you're sending the notification. Ensure that the to field is being set correctly. For example, when using a Mailable:
Mail::to($recipient)->send(new YourMailableClass($data));

Or when using a Notification:

Notification::route('mail', $recipient)->notify(new YourNotification($data));
  1. Check the Notification Class: If you're using Laravel's Notification system, ensure that the toMail method in your notification class correctly sets the recipient.
public function toMail($notifiable)
{
    return (new MailMessage)
                ->to($notifiable->email) // Make sure this line is correct
                // ...
}
  1. Test with a Simple Email: Try sending a simple email to isolate the problem. If this works, the issue might be with the notification class or how it's being called.
Mail::raw('This is a test email', function ($message) {
    $message->to('[email protected]')->subject('Test Email');
});
  1. Check the Logs: Laravel logs can provide more insight into what's going wrong. Check the logs in storage/logs/laravel.log for any additional error messages.

  2. Review the GitHub Issue: Since you've mentioned a GitHub issue, make sure you've read through all the comments as sometimes solutions are found later in the thread.

If none of these steps resolve the issue, it might be helpful to post your notification code and any relevant configuration files on the forum for more specific guidance. Remember to redact any sensitive information before posting.

Hey @psizer10 thanks for this - I'm seeing the issue still. Should this new config go into config/services.php or config/mail.php, or both? Currently Laravel10, symfony/mailgun-mailer 7.0.4

@OK200Paul apology for the delay.

I believe config/mail.php is the only place where you need to paste the mail-related configuration.
