Mailgun emails not sending from Laravel 8 Valet app - php

Question

Here's my relevant .env:
MAIL_MAILER=mailgun
MAIL_HOST=smtp.mailgun.org
MAIL_PORT=587
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_ADDRESS=null
MAIL_FROM_NAME="${APP_NAME}"
MAILGUN_DOMAIN=https://api.mailgun.net/v3/mail.example.com
MAILGUN_SECRET=fb...a1
Note: I use example.com as an example above, but I've put my actual domain name there. I do not get any errors from the Laravel app, and I do not see anything in the logs on the Mailgun dashboard. My domain is verified. fb...a1 is also the redacted API code, I of course use my full API code I get from the mailgun dashboard.
config/mail.php:
<?php
return [
'default' => env('MAIL_MAILER', 'mailgun'),
'mailers' => [
'mailgun' => [
'transport' => 'mailgun',
],
],
];
config/services.php:
'mailgun' => [
'domain' => env('MAILGUN_DOMAIN'),
'secret' => env('MAILGUN_SECRET'),
'endpoint' => env('MAILGUN_ENDPOINT', 'api.mailgun.net'),
],
In my controller I have:
$email = $validated['email']; // I've verified this is my actual email
Mail::to($email)->send(new OrderCreated());
app/Mail/OrderCreated.php:
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
class OrderCreated extends Mailable
{
use Queueable, SerializesModels;
public function __construct()
{
//
}
public function build()
{
return $this
->from('no-reply#example.com')
->markdown('emails.order-created');
}
}
And finally, resources/views/emails/order-created.blade.php:
#component('mail::message')
# Order Confirmation
This email is test.
#endcomponent
I'm using Laravel 8.14.0 and Valet 2.13.0, so I'm testing it locally with an https://my-app.test domain. The app is using InertiaJS, in case that makes any difference. The controller code runs without error, but I see no logs on my mailgun dashboard and the email never arrives in my inbox. I have no idea what's wrong or how to debug this.
UPDATE:
I've noticed if I set MAILGUN_DOMAIN and MAILGUN_SECRET to null, I get the same behaviour as above. If I set MAILGUN_DOMAIN to a nonsense value like abcd I get the following error:
GuzzleHttp\Exception\ClientException
Client error: `POST https://api.mailgun.net/v3/abcd/messages.mime` resulted in a `401 UNAUTHORIZED` response: Forbidden
And if I set MAILGUN_SECRET to abcd it works as originally described (no error, but also no email).

These days I've worked with mailgun. It was on Laravel 7, and it worked perfectly. I dont think that it will cause a problem for v8.
Actually I've sent emails from controller, but you can implement the same for you as you want.
So I'll share my experience anyway.
.env
#MAIL_DRIVER=mailgun
MAIL_MAILER=mailgun
MAIL_HOST="smtp.mailgun.org"
MAIL_PORT=587
MAIL_USERNAME="postmaster#sandbox********************************.mailgun.org"
MAIL_PASSWORD="123456"
MAIL_ENCRYPTION=tls
MAILGUN_DOMAIN="sandbox********************************.mailgun.org"
MAILGUN_SECRET="key-********************************"
MAIL_FROM_NAME="ProjectName"
MAIL_FROM_ADDRESS="no-reply#yourfuturesite.com"
MAIL_ENV=test
MAIL_TEST="recipient#yourfuturesite.com"
#MAIL_LOG_CHANNEL
#MAILGUN_ENDPOINT="api.eu.mailgun.net"
config/mail.php
<?php
return [
'default' => env('MAIL_MAILER'),
'mailers' => [
'smtp' => [
'transport' => 'smtp',
'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
'port' => env('MAIL_PORT', 587),

'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'timeout' => null,
'auth_mode' => null,
],
'ses' => [
'transport' => 'ses',
],
'mailgun' => [
'transport' => 'mailgun',
'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
'port' => env('MAIL_PORT', 587),
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'timeout' => null,
'auth_mode' => null,
],

'transport' => 'postmark',
],

],
'array' => [
'transport' => 'array',
],
],
'from' => [
'address' => env('MAIL_FROM_ADDRESS'),
'name' => env('MAIL_FROM_NAME'),
],
'markdown' => [
'theme' => 'default',
'paths' => [
resource_path('views/vendor/mail'),
],
],
// CUSTOM CONFIGS
'mail_env' => env('MAIL_ENV'), // 'local' for testing via mailgun, 'production' for all mails
'mail_test' => env('MAIL_TEST'), // test email for 'local' testing
// ADDITIONAL UNNECESSARY CONFIGS

// 'sendmail' => '/usr/sbin/sendmail -t-i',
// 'pretend' => false,

// 'pretend' => false,
];
config/services.php (the same as you have)
Controller
try {
$name = array_key_exists('first_name', $email_data) ? $email_data['first_name'] : $email_data['name'];
Mail::send('emails.confirm-registration', [
'role' => $email_data['role'],
'name' => $name,
'email' => $email_data['email'],
'confirm_registration' => route('front.auth.confirm_registration', ['registration_token' => $email_data['registration_token']]),
], function ($message) use ($email_data, $name) {
$to = (config('mail.mail_env') == 'prod' || config('mail.mail_env') == 'production') ? $email_data['email'] : config('mail.mail_test');
$message
->subject(config('app.name') . ": Email Confirmation")
->from(config('mail.from.address'), config('mail.from.name'))
->to($to, $name);
});
return true;
}
catch(\Exception $e) {
// TODO: report all the "$e->message"s like this
return false;
}
resources/views/emails/confirm-registration.php
<a href="{{ route('front.main') }}" target="_blank">
<img label="logo" alt="{{ config('app.name') }}"
src="{{ $message->embed(public_path('images/logo.svg')) }}" width="128" height="96">
</a>
<p>{{ $name }}</p>
<p>{{ $confirm_registration }}</p>
<p>© {{ date("Y") == 2020 ? '2020' : '2020-' . date("Y") }} {{ config('app.name') }}</p>
This is just my example, so there you may need to replace as you want.
Just pay attention to "config/mail.php" file. I think there you need to set some additional props. (Also don't forget to reload your cache after these last config changes: "php artisan config:cache")
