我一次又一次嘗試測試從本地主機發(fā)送電子郵件，但我仍然不能。我不知道該怎么做。我嘗試搜索以找到解決方案，但找不到。我編輯了config / mail.php：<?phpreturn [    /*    |--------------------------------------------------------------------------    | Mail Driver    |--------------------------------------------------------------------------    |    | Laravel supports both SMTP and PHP's "mail" function as drivers for the    | sending of e-mail. You may specify which one you're using throughout    | your application here. By default, Laravel is setup for SMTP mail.    |    | Supported: "smtp", "mail", "sendmail", "mailgun", "mandrill", "ses", "log"    |    */    'driver' => env('MAIL_DRIVER', 'smtp'),    /*    |--------------------------------------------------------------------------    | SMTP Host Address    |--------------------------------------------------------------------------    |    | Here you may provide the host address of the SMTP server used by your    | applications. A default option is provided that is compatible with    | the Mailgun mail service which will provide reliable deliveries.    |    */    'host' => env('MAIL_HOST', 'smtp.gmail.com'),    /*    |--------------------------------------------------------------------------    | SMTP Host Port    |--------------------------------------------------------------------------    |    | This is the SMTP port used by your application to deliver e-mails to    | users of the application. Like the host we have set this value to    | stay compatible with the Mailgun e-mail application by default.    |    */    'port' => env('MAIL_PORT', 587),];`
