Mail Not Sending via Mailgun API Laravel 8 - php

Question

I am trying to send mail via the mailgun API from my controller but the mail is not reaching mailgun and I am not getting any error messages/logs.
This is in my .env:
MAIL_MAILER=mailgun
MAILGUN_DOMAIN=subdomain.domain.ca
MAILGUN_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxx
This is in my services.php:
<?php
return [
/*
|--------------------------------------------------------------------------
| Third Party Services
|--------------------------------------------------------------------------
|
| This file is for storing the credentials for third-party services such
| as Mailgun, Postmark, AWS, and more. This file provides the de facto
| location for this type of information, allowing packages to have
| a conventional file to locate the various service credentials.
|
*/
'mailgun' => [
'domain' => env('subdomain.domain.ca'),
'secret' => env('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'),
],
'postmark' => [
'token' => env('POSTMARK_TOKEN'),
],
'ses' => [
'key' => env('AWS_ACCESS_KEY_ID'),
'secret' => env('AWS_SECRET_ACCESS_KEY'),
'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
],
];
This is in my mail.php:
<?php
return [
/*
|--------------------------------------------------------------------------
| Default Mailer
|--------------------------------------------------------------------------
|
| This option controls the default mailer that is used to send any email
| messages sent by your application. Alternative mailers may be setup

This is how I am sending the mail in my controller:
Mail::send('emailtemplates.trackeremail', $data, function($message)use($data, $pdf) {
$message->to($data["toaddress"])
->cc($data["ccaddress"])
->subject($data["title"])
->attachData($pdf->output(), "PDFName.pdf");
});
This is working when I send to mailgun via SMTP in my local environment but I am unfortunately limited to shared hosting that does not allow 3rd party SMTP and I need to switch to the API method for production. I have gone through many tutorials and questions on this site (and others) related but nothing has solved my issue.
I always run php artisan config:clear after any kind of .env change.
Is there anything else that I can be doing to even get an error message or further debug this? Any help would be appreciated.

Answer 1

It might possibly be the port, host, encryption, and mail from:
Keep these as is in your .env:
MAIL_MAILER=mailgun
MAIL_HOST=smtp.mailgun.org
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
Enter these in your .env:
MAIL_FROM_NAME=YourNameHere
MAIL_FROM_ADDRESS=enter#theemail.com
MAIL_FROM=enter#theemail.com
MAILGUN_DOMAIN=subdomain.domain.ca
MAILGUN_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxx
Update services.php with:
'mailgun' => [
'domain' => env('MAILGUN_DOMAIN'),
'secret' => env('MAILGUN_SECRET'),
'endpoint' => env('MAILGUN_ENDPOINT', 'api.mailgun.net'),
],
Update mail.php with adding:
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'port' => env('MAIL_PORT', 587),

After going over this with A2 Hosting's technical support it turns out that this is just not possible with their shared hosting, I was informed that "Mailgun only supports the standard SMTP ports, so it is not supported on our shared server".
