嗨，我正在尝试通过java代码发送电子邮件，我已经安装了cmail服务器来发送电子邮件，但我无法发送电子邮件，我该如何发送电子邮件
这是我的代码
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class SendEmail
{
public static void main(String [] args){
String to = "shaktisharma27789@gmail.com";//change accordingly
String from = "admin@shakti-pc.com";
String host = "localhost";//or IP address
//Get the session object
Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", host);
Session session = Session.getDefaultInstance(properties);
//compose the message
try{
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject("Ping");
message.setText("Hello, this is example of sending email ");
// Send message
Transport.send(message);
System.out.println("message sent successfully....");
}catch (MessagingException mex) {mex.printStackTrace();}
}
}
当我运行我的程序时，我收到以下异常
com.sun.mail.smtp.SMTPSendFailedException: 550 admin@shakti-pc.com is not authorized.(WRONG SENDER MAILADDR)
;
nested exception is:
com.sun.mail.smtp.SMTPSenderFailedException: 550 admin@shakti-pc.com is not authorized.(WRONG SENDER MAILADDR)

我怎样才能实现我的输出？
提前致谢
最佳答案
您尚未在其中输入密码字段。此外，您还没有指定您的主机。如果您从本地主机发送电子邮件，则应该指定它。此外，如果您通过 gmail 服务器发送邮件，则应使用“smtp.gmail.com”。 检查http://www.tutorialspoint.com/servlets/servlets-sending-email.htm为了澄清你的问题。通过本教程，您也可以发送带有附件的电子邮件。如果您需要jsp代码，我可以为您提供。
