没有发件人地址就无法发送消息-Laravel验证电子邮件

Question

我希望向每位新注册用户发送一封验证电子邮件，并且已经执行了[Laravel文档] [1]中的步骤。

下面是我的User Class

<?php

namespace App;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Passport\HasApiTokens;

//class User extends Authenticatable
class User extends Authenticatable implements MustVerifyEmail
{
    use HasApiTokens, Notifiable;

    
    protected $guarded = [];

    
    protected $hidden = [
        'password', 'remember_token',
    ];

    
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    
}

web.php路由

<?php

use Illuminate\Support\Facades\Route;


Auth::routes(['verify' => true]);

但是注册后，它将发送结构化的欢迎电子邮件，但不发送验证电子邮件，而是引发以下错误。

Swift_TransportException
Cannot send message without a sender address

我在做什么不正确？
