從java發送電子郵件

Question

當我使用Java郵件驗證時，發送來自Java的電子郵件時出現問題。我不知道我得到以下例外的方式：

javax.mail.AuthenticationFailedException: 530 Access denied 

我將在下面顯示整個代碼。你能告訴我我做錯了什麼嗎？
請注意，在添加身份驗證之前，一切正常。 另外，你知道是否有可能在兩個不同的域名之間發送電子郵件（例如Gmail到雅虎）？

Answer 1

這是我的代碼，我曾經通過我的Gmail帳戶發送電子郵件，在我的JSP的學術項目：

package my_util; 

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

public class Mail 
{ 
    private String d_email = "myemailid@gmail.com", 
        d_password = "mypassword", 
        d_host = "smtp.gmail.com", 
        d_port = "465"; 


    public boolean sendMail(String strTo, String strSubject, String strBody){ 

     Properties props = new Properties(); 
     props.put("mail.smtp.user", d_email); 
     props.put("mail.smtp.host", d_host); 
     props.put("mail.smtp.port", d_port); 
     props.put("mail.smtp.starttls.enable","true"); 
     props.put("mail.smtp.auth", "true"); 
     props.put("mail.smtp.socketFactory.port", d_port); 
     props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
     props.put("mail.smtp.socketFactory.fallback", "false"); 

     try 
     { 
      Session session = Session.getDefaultInstance(props, null); 
      MimeMessage msg = new MimeMessage(session); 
      msg.setText(strBody); 
      msg.setSubject(strSubject); 
      msg.setFrom(new InternetAddress(d_email)); 
      msg.addRecipient(Message.RecipientType.TO, new InternetAddress(strTo)); 
      msg.saveChanges(); 

      Transport transport = session.getTransport("smtp"); 
      transport.connect(d_host, d_email, d_password); 
      transport.sendMessage(msg, msg.getAllRecipients()); 
      transport.close(); 
      return true; 
     } 
     catch (Exception mex) 
     { 
      mex.printStackTrace(); 
      return false; 
     } 
    } 

} 

我希望它可以幫助你。 :)
