Laravel - Doesn't send messages from the site

Question

Laravel 7.0

Sending email from localhost does not work. He writes that he cannot send a message without an email, but I put all the fields with emails. Created everything with docs.laravel.

Route\web.php

Route::get('contact', 'ContactsController@index')->name('contacts'); // ContactsPages
Route::post('contact/send',  'MailSetting@send_form'); // ContactsPages(FORM_FeedBack)

App\Http\Controller\MailSetting

<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\Mail;
use Illuminate\Http\Request;
use App\Mail\MailClass;

class MailSetting extends Controller
{
    public function send_form(Request $request)
    {
        $name = $request->name;
        $email = $request->email;
        $message = $request->message;

        Mail::to('[email protected]')->send(new MailClass($name, $email, $message));
    }
}

App\Mail\MailClass

<?php

namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class MailClass extends Mailable
{
    use Queueable, SerializesModels;

    protected $name;
    protected $email;
    protected $message;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($name, $email, $message)
    {
        $this->name = $name;
        $this->email = $email;
        $this->message = $message;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->view('emails.contact-mail')
            ->with([
            'name' => $this->name,
            'email' => $this->email,
            'message' => $this->message,
        ])
        ->subject('New MESSAGE ');
    }
}

                                <div class="col-lg-12">
                                    <textarea name="message" id="message" placeholder="Your message"></textarea>
</div>
<div class="col-lg-12">
<button type="send">Send message</button>
                                </div>
                            </div>
                        </div>
                    </form>
                </div>

email_view

Name   : {{ json_encode($name,TRUE)}} <br>
Email  : {{ json_encode($email,TRUE)}} <br>
Message: {{ json_encode($message,TRUE)}} <br>

After the error appeared for the first time, I decided that I could change the settings on Gmail, changed them, but there another error appears.

Answer 1

From Address is required (A MUST) for sending emails - even when the host is set to mailtrap.io

It can be set globally for the app in the .env file

[email protected]

Or it can be set/overridden per Mailable class in the build method

public function build()
{
    return $this->view('emails.contact-mail')
        ->with([
            'name' => $this->name,
            'email' => $this->email,
            'message' => $this->message,
        ])
        ->subject('New MESSAGE ')
        ->from('[email protected]');
}
