Laravel 5.8-验证和欢迎电子邮件未发送

Question

当我在运行Laravel 5.8的网站上注册用户时，未向用户发送欢迎电子邮件和验证电子邮件，但是当我从“重置密码”页面检查重置密码邮件时，效果很好。

这是我的ActivationMailClient.php

<?php

namespace App\Mail;

use App\Helpers\Themes;
use App\Models\Setting;
use App\User;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class ActivationClientMail extends Mailable
{
    use Queueable, SerializesModels;
    protected $user;

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

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        $crypt_email = bcrypt($this->user->email);
        return $this->view('emails.active_account')
            ->subject('Activation - Active Account')
            ->to($this->user->email, $this->user->first_name . ' ' . $this->user->last_name)
            ->from('contact@trvtour.com', 'mywebsiteName Activation')
            ->with([
                'crypt_email' => $crypt_email,
                'user' => $this->user,
                'first_name' => $this->user->first_name,
                'reset_link' => url('active_account?key=' . $crypt_email . '&u=' . $this->user->id),
                'site_name' => Setting::getByKey('site_name')->value
            ]);
    }
}

这是我的ResetPassword.php

<?php

namespace App\Mail;

use App\Helpers\Themes;
use App\Models\Setting;
use App\User;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class ResetPassword extends Mailable
{
    use Queueable, SerializesModels;

    protected $user;

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

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        $crypt_email = Themes::myCrypt($this->user->email);
        return $this->view('emails.reset_password')
            ->to($this->user->email, $this->user->first_name . ' ' . $this->user->last_name)
            ->from('contact@trvtour.com', 'mywebsiteName Reset Password')
            ->with([
                'crypt_email' => $crypt_email,
                'user' => $this->user,
                'reset_link' => url('panel/update_password/' . $crypt_email),
                'site_name' => Setting::getByKey('site_name')->value
            ]);
    }
}

我已经清除了我的laravel应用程序的缓存，但是问题仍然存在，请您帮我解决这个问题？
