如何使用 Mailgun 和 Laravel 发送电子邮件？

Question

I have a Contact page with a Contact Form on it. I'm using Laravel and Vue js. I've been sending test emails using Mailtrap on my localhost and everything works great. After deploying my App to GoDaddy, I am now using Mailgun to send email. I removed these settings in my .env file:

#MAIL_MAILER=smtp
#MAIL_HOST=smtp.mailtrap.io
#MAIL_PORT=2525
#MAIL_USERNAME=xxxxxx
#MAIL_PASSWORD=xxxxxx
#MAIL_ENCRYPTION=tls

And now I have only these settings in my .env file:

MAIL_MAILER=mailgun
MAILGUN_DOMAIN=highrjobs.com
MAILGUN_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

I'm getting this error on Live Production site, after I click Submit, it says: server error .

I looked in storage/logs/laravel.log file and it gives me this error: prod.ERROR: Connection could not be established with host smtp.mailtrap.io :stream_socket_client(): unable to connect to tcp://smtp.mailtrap.io:2525 (Connection refused) {"exception":"[object] (Swift_TransportException(code: 0): Connection could not be established with host smtp.mailtrap.io :stream_socket_client(): unable to connect to tcp://smtp.mailtrap.io:2525 (Connection refused) at /home/ymq6es2sf6km/highrjobs/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:269)

Why is it still trying to connect to mailtrap via smtp, I'm overriding these settings in my .env file as listed above.

Here is my config.php file:

<?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
    | and used as needed; however, this mailer will be used by default.
    |
    */

    'default' => env('MAIL_MAILER', 'mailgun'),

        'smtp' => [

        'paths' => [
            resource_path('views/vendor/mail'),
        ],
    ],

];

and I added this in services.php:

'mailgun' => [
        'domain' => env('MAILGUN_DOMAIN'),
        'secret' => env('MAILGUN_SECRET'),
        'endpoint' => env('MAILGUN_ENDPOINT', 'api.mailgun.net'),
    ],

Can somebody please help?
