我用https://www.smtper.net/测试了我的凭据，它们可完美地用于端口25（未加密）和端口465（已加密）。我的Laravel配置文件中可能有一个错误：
。env：
MAIL_DRIVER=smtp
MAIL_HOST=###.netcup.net
MAIL_PORT=25
[email protected]
MAIL_PASSWORD=#########
[email protected]
MAIL_FROM_NAME="me"
MAIL_ENCRYPTION=null
我也尝试过
MAIL_DRIVER=smtp
MAIL_HOST=###.netcup.net
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=#########
[email protected]
MAIL_FROM_NAME="me"
MAIL_ENCRYPTION=ssl
config / mail.php：
'mailers' => [
'smtp' => [
'transport' => 'smtp',
'host' => env('MAIL_HOST', '###.netcup.net'),
'port' => env('MAIL_PORT', 25),
'encryption' => env('MAIL_ENCRYPTION', 'null'),
'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
'timeout' => null,
'auth_mode' => null,
],
'from' => [
'address' => env('MAIL_FROM_ADDRESS', '[email protected]'),
'name' => env('MAIL_FROM_NAME', 'me'),
],
端口25和465这两个请求都在Laravel中带来此错误：

此问题在这里发生过几次，但没有一个答案有效。这是在Laravel 7的原始安装中发生的，除了这些配置文件外，没有任何修改。有人有主意吗？谢谢。
