通过smtp发送邮件时，Laravel 5 Error 500

Question

我想在我的网站上创建一个简单的联系表格，用户会收到确认邮件，我会收到用户发送给我的文本。但不知怎的，它不起作用，我不知道为什么。

ContactController：

    public function sendMail(Request $request){

    $this->validate($request, [
        'email' => 'required|email',
        'name' => 'required',
        'subject' => 'required',
        'text' => 'min:10 | max:65536'
    ]);

    $data = [
        'email' => $request->input('email'),
        'name' => $request->input('name'),
        'subject' => $request->input('subject'),
        'text' => $request->input('text')
    ];

    Mail::to($request->input('email'))->send(new RequestReceived($data));
    Mail::to('test@velocityvideogroup.com')->send(new ContactEmail($data));

    $request->session()->flash('success', 'Request has been successfully sent!');
    return redirect('/contact');
}
}

MailClasses：

ConfirmationMail：

class RequestReceived extends Mailable{

use Queueable, SerializesModels;


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

/**
 * Build the message.
 *
 * @return $this
 */
public function build()
{
    return $this->markdown('emails.received')
                ->subject('Velocity | Request received!')
                ->with([
                    'name' => $this->data['name'],
                    'text' => $this->data['text']
                ]);
    }
}

邮件我应该得到：

class ContactEmail extends Mailable
{
use Queueable, SerializesModels;

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

/**
 * Build the message.
 *
 * @return $this
 */
public function build()
{
    return $this->markdown('emails.contactemail')
                ->from($this->data['email'])
                ->subject($this->data['subject'])
                ->with([
                    'name' => $this->data['name'],
                    'text' => $this->data['text']
                ]);
    }
}
