这是我在日志中发现的: 日志告诉我无法访问 gmx.net 的 DSN,日志文件如下所示:

  $from = 'noreply@MYWEBSITEURL.de'; 
  $fromName = 'MYWEBSITENAME';

  ';

  $semi_rand = md5(time());  
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";  

  // Headers for attachment  
  $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\"";

  $message = "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"UTF-8\"\n" .

      $fp =    @fopen($file,"rb"); 
      $data =  @fread($fp,filesize($file)); 

      @fclose($fp); 
      $data = chunk_split(base64_encode($data));

      "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; 
    } 
  } 
  $message .= "--{$mime_boundary}--"; 
  $returnpath = "-f" . $from; 

  // Send email 
  $mail = @mail($to, $subject, $message, $headers, $returnpath);  

  // Email sending status 
  echo $mail?"send":"send_error";

这适用于 gmail.com 但不适用于 gmx.net 或 web.de

希望你能帮我解决这个问题,谢谢你的时间。

我通过向我的域添加一个反向 DNS 条目来解决这个问题,以将 IP 解析到发送电子邮件的我的域。这解决了我的问题,现在所有电子邮件都已送达:)
