JavaMail SocketException:连接重置

我试图通过JavaMail API发送电子邮件，但最终收到了SocketException：连接重置

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;

public class SendMailSSL {
 public static void main(String[] args) {

Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class",
    "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");

     Authenticator auth = new Authenticator() {

             @Override
             protected PasswordAuthentication getPasswordAuthentication() {
                 return new PasswordAuthentication("userName@gmail.com","gmailPassword");
             }
         };

    Session session = Session.getDefaultInstance(props,auth);


    try {

    Message message = new MimeMessage(session);
    Address sender  = new InternetAddress("any@...");
    message.setFrom(sender);

    String recipients = "email1@...,email2@...,email2@...";
    String[] toList = recipients.split(",");
    System.out.println(toList.length);
    Address[] addressTo = new InternetAddress[toList.length];

    for(int i = 0; i < toList.length; i++){
    addressTo[i] = new InternetAddress(toList[i]);  
    }

    for( int i=0; i < addressTo.length; i++) { // changed from a while loop
            message.addRecipient(Message.RecipientType.TO, addressTo[i]);
        }


    message.setSubject("Testing Subject 5");
    message.setText("Dear Message ," +
    "\n\n HELLO, please! \n https://192.168.192.120:8181/centralWeb");
    System.out.println("SENDING MAIL......... " + new Date().toString());

    message.setHeader("Content-type", "text/html; charset=UTF-8");
    Transport.send(message);

    System.out.println("Done  " + new Date().toString());

    } catch (MessagingException e) {
    throw new RuntimeException(e);
    }

 }
}

我曾尝试禁用IPv6并关闭防火墙，但问题依然存在。如果有必要的话，我使用的是Windows7x64

感谢所有能够帮助我解决此问题的人。

请尝试以下JavaMail常见问题解答中的调试技巧：

此外，您可能希望纠正这些问题，尽管我认为它们与您的问题无关。

Transport.send（…）

看起来可疑。您在代码中的什么位置连接到服务器？看到@chr中的代码了吗？是的，你是对的。令人惊讶的是，出于某种原因，该代码确实有效。（导致套接字异常的是我的防病毒软件中一个愚蠢的smtp传出筛选器）。感谢您指出，我将添加您指出的代码。实际上，在链接中，我的代码中有一些提到的错误。谢谢，我会修改代码的。顺便说一句，我成功了。原来是我的防病毒软件中的smtp传出筛选器阻止了连接。防病毒软件也是我的问题。。。！
