fsockopen():php_network_getaddresses:getaddrinfo 失败:名称或服务未知

fsockopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known

我无法将表单内容发送到电子邮件。我收到以下错误:

: Warning
Message: fsockopen(): php_network_getaddresses: getaddrinfo failed:Name or service not known

Filename: libraries/Email.php

Line Number: 1986

Severity: Warning

Message: fsockopen(): unable to connect to ssl://smtp.123mailsetup.com:25   (php_network_getaddresses: getaddrinfo failed: Name or service not known)

Filename: libraries/Email.php

   Line Number: 1986

我的台词1986是

$this->smtp_timeout);

我控制器中的部分代码

$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'smtp.xxxx.com',
'smtp_port' => 465,
'smtp_user' => 'xxxxx@xxx.com',
'smtp_pass' => 'xxxxxxxx',
'mailtype'  => 'html', 
'charset'   => 'iso-8859-1'
);
                $this->load->library('email', $config);
                $this->email->from('xxxxx@xxx.com', 'Mailsetup');
                $this->email->to($email); 

                $this->email->subject('Domain transfer');
                $this->email->message( '<html><body>Domain to be transfered        '.$domain.' <br> Domain owner '.$name.' , <br> email '.$email.'

                </body></html>' );   

                $this->email->send();

使用PHP 邮寄程序See Here

$mail = new PHPMailer(true);

$auth = true;

if ($auth) {
  $mail->IsSMTP(); 
  $mail->SMTPAuth = true; 
  $mail->SMTPSecure = "ssl"; 
  $mail->Host = "smtp.xxxx.com"; 
  $mail->Port = 465; 
  $mail->Username = "username@host.com"; 
  $mail->Password = "xxxxxxxxxxxx"; 
}

$mail->AddAddress("xxxxxxxx@xxxxxx.com");
$mail->SetFrom("JohnDeo@xxx.com", "John Deo");
$mail->isHTML(true);
$mail->Subject = "Test Email";
$mail->Body = "Hello World";

try {
  $mail->Send();
  return true;
} catch(Exception $e){
  echo $mail->ErrorInfo;
}
