无法使用Laravel 5.5 Swiftmailer连接TLS加密

我试图用Laravel内置的swift邮件发送邮件，但每次都会出现“无法连接TLS加密”错误。 下面是我的.env文件：

MAIL_DRIVER=smtp
MAIL_HOST=smtp.office365.com
MAIL_PORT=587
MAIL_USERNAME=myemailaddress
MAIL_PASSWORD=mypassword
MAIL_ENCRYPTION=tls

我的config/mail.php文件如下：

'driver' => env('MAIL_DRIVER', 'smtp'),

    'host' => env('MAIL_HOST', 'smtp.office365.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => [
        'address' => env('MAIL_FROM_ADDRESS', 'myemailaddress'),
        'name' => env('MAIL_FROM_NAME', ''),
    ],

    'encryption' => env('MAIL_ENCRYPTION', 'tls'),

    'username' => env('MAIL_USERNAME','myemailaddress'),

    'password' => env('MAIL_PASSWORD','mypassword'),


    'sendmail' => '/usr/sbin/sendmail -bs',

    'markdown' => [
        'theme' => 'default',

        'paths' => [
            resource_path('views/vendor/mail'),
        ],
    ],

];

if ($loan->save()) {
        $name = staff::select('staff_name')->where('staff_id','=',$id)->first();
        $data = array(
          'Name' => $name,
          'Amount' => $request->input('amount'),
          'Tenor' => $request->input('tenor'),
          'Purpose' => $request->input('purpose')
        );

        Mail::send('emails.loanrequest', $data, function($message){
          $message->from('myaddress');
          $message->to('myemailaddress');
          $message->subject('New Loan Request');
        });
      }

我发起邮件发送的控制器如下所示：

'driver' => env('MAIL_DRIVER', 'smtp'),

    'host' => env('MAIL_HOST', 'smtp.office365.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => [
        'address' => env('MAIL_FROM_ADDRESS', 'myemailaddress'),
        'name' => env('MAIL_FROM_NAME', ''),
    ],

    'encryption' => env('MAIL_ENCRYPTION', 'tls'),

    'username' => env('MAIL_USERNAME','myemailaddress'),

    'password' => env('MAIL_PASSWORD','mypassword'),


    'sendmail' => '/usr/sbin/sendmail -bs',

    'markdown' => [
        'theme' => 'default',

        'paths' => [
            resource_path('views/vendor/mail'),
        ],
    ],

];

if ($loan->save()) {
        $name = staff::select('staff_name')->where('staff_id','=',$id)->first();
        $data = array(
          'Name' => $name,
          'Amount' => $request->input('amount'),
          'Tenor' => $request->input('tenor'),
          'Purpose' => $request->input('purpose')
        );

        Mail::send('emails.loanrequest', $data, function($message){
          $message->from('myaddress');
          $message->to('myemailaddress');
          $message->subject('New Loan Request');
        });
      }

任何帮助，将使这项工作将不胜感激。谢谢..

显然，是我的代理服务器阻止了我的连接。一旦我切换了连接，它就工作了。

看起来SMTP上没有启用TLS。您是否可以尝试不使用该选项，或者尝试在SMTP上启用TLSserver@FleminAdambukulam我尝试在没有TLS的情况下发送时收到此错误消息。“客户端未通过身份验证，无法发送匿名邮件”@FleminAdambukulam显然，是我的代理服务器阻止了我的连接。。谢谢你的帮助
