Question

我在eclipse中编写这个应用程序我添加了所有的jar文件。我正在粘贴代码和错误。请让我知道我应该做些什么来正确运行应用程序。

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class SendMail
{
  public static void main(String [] args)
  {
    SendMail sm=new SendMail();
    try{
     sm.postMail(new String[]{"xyz@yahoo.com"},"hi","hello","abc@gmail.com");
    }
    catch(MessagingException e)
    {
        e.printStackTrace();
    }
    }


public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException
{
    boolean debug = false;

     //Set the host smtp address
     Properties props = new Properties();
     props.put("mail.smtp.starttls.enable","true");
     props.put("mail.smtp.host", "smtp.gmail.com");
        props.setProperty("mail.smtp.port", "25");

    // create some properties and get the default Session
    Session session = Session.getDefaultInstance(props, null);
    session.setDebug(debug);

    // create a message
    Message msg = new MimeMessage(session);

    // set the from and to address
    InternetAddress addressFrom = new InternetAddress(from);
    msg.setFrom(addressFrom);

    InternetAddress[] addressTo = new InternetAddress[recipients.length]; 
    for (int i = 0; i < recipients.length; i++)
    {
        addressTo[i] = new InternetAddress(recipients[i]);
    }
    msg.setRecipients(Message.RecipientType.TO, addressTo);


    // Optional : You can also set your custom headers in the Email if you Want
    msg.addHeader("MyHeaderName", "myHeaderValue");

    // Setting the Subject and Content Type
    msg.setSubject(subject);
    msg.setContent(message, "text/plain");
    Transport.send(msg);
}
}

错误：

Answer 1

实际上，您还必须在使用smtps时设置smtps属性。

只需将邮件属性设置为包括：

mail.smtps.host
mail.smtps.auth

Answer 2

您尝试通过需要加密连接的连接发送邮件（在这种情况下为TLS）。

这个太阳论坛有几个你可以尝试的解决方案： http://forums.sun.com/thread.jspa?threadID=617974

Answer 3

对于javamail到GMail SMTP，我使用以下属性：

mail.smtp.host="smtp.gmail.com"
mail.smtp.port="587"
mail.smtp.auth="true"
mail.smtp.starttls.enable="true"

我不知道GMail在25号接受邮件。也许这就是你问题的根源。

显然，您仍需要执行身份验证，通常是mail.smtp.user和mail.smtp.password。

这个code.Runtime错误有什么问题
