Mailgun emails not going out - php

Question

I'm creating a verification email, however the mail isn't going out and I don't receive any errors.
My call to send the email:
public function register(Request $request)
{
$this->validator($request->all())->validate();
event(new Registered($user = $this->create($request->all())));
Mail::to($user->email)
->queue(new VerifyEmail($user));
return $this->registered($request, $user)
?: redirect($this->redirectPath());
}
here's my email build function:
public function build()
{
return $this->view('emails.account.verify_email')
->with([
'id' => $this->user->id,
'firstname' => $this->user->firstname,
'token' => $this->user->email_verification_token,
]);
}
I installed guzzlehttp/guzzle
and changed my files:
ENV (not sure of the port setting)
MAIL_DRIVER=mailgun
MAIL_HOST=smtp.mailgun.org
MAIL_PORT=587
MAIL_USERNAME=postmaster#sandbox...655.mailgun.org
MAIL_PASSWORD=Default mailgun sandbox Password
MAIL_ENCRYPTION=tls
config/services
'mailgun' => [
'domain' => env('sandbox...655.mailgun.org'),
'secret' => env('key-...'),
],
config/mail
<?php
return [
'driver' => env('MAIL_DRIVER', 'mailgun'),
'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
'port' => env('MAIL_PORT', 587),
'from' => [
'address' => env('MAIL_FROM_ADDRESS', 'hello#example.com'),
'name' => env('MAIL_FROM_NAME', 'Example'),
],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'sendmail' => '/usr/sbin/sendmail -bs',
'markdown' => [
'theme' => 'default',
'paths' => [
resource_path('views/vendor/mail'),
],
],
];
I don't receive any errors, however there are no outgoing mails when I check the mailgun dashboard

Answer 1

Your services config file is wrong:
'mailgun' => [
'domain' => env('sandbox...655.mailgun.org'),
'secret' => env('key-...'),
],
You're trying to look up the values from the .env file here. Should reference the keys, not the values. For instance:
'mailgun' => [
'domain' => env('MAIL_DOMAIN'),
'secret' => env('MAIL_SECRET'),
],
And then add them to your .env file:
MAIL_DOMAIN=sandbox...655.mailgun.org
MAIL_KEY=key-...
I'm assuming the rest is correct but I don't know for certain. :)
