这是我的代码
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class SendMail
{
String host, port, emailid,username, password;
Properties props = System.getProperties();
Session l_session = null;
public SendMail()
{
host = "smtp.mail.yahoo.com";
port = "587";
emailid = "xxx@yahoo.com";
username = "xxx@yahoo.com";
password = "xxxxx";
emailSettings();
createSession();
sendMessage("xxx@yahoo.com", "yyyy@yahoo.com","Test","test Mail");
}
public void emailSettings()
{
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "false");
props.put("mail.smtp.port", port);
}
public void createSession()
{
l_session = Session.getInstance(props,new javax.mail.Authenticator()
{
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(username, password);
}
});
l_session.setDebug(true); // Enable the debug mode
}
public boolean sendMessage(String emailFromUser, String toEmail, String subject, String msg)
{
try
{
MimeMessage message = new MimeMessage(l_session);
emailid = emailFromUser;
message.setFrom(new InternetAddress(this.emailid));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
message.setSubject(subject);
message.setContent(msg, "text/html");
//message.setText(msg);
Transport.send(message);
System.out.println("Message Sent");
}
catch (MessagingException mex)
{
mex.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
}//end catch block
return true;
}
public static void main(String args[])
{
new SendMail();
}
}
当我运行此代码时,我得到 com.sun.mail.smtp.SMTPSendFailedException:530 5.7.1需要验证这个错误。我使用PasswordAuthentication。我不知道为什么会出现这种异常。请问有谁能告诉我如何克服这个错误?

请试试下面的代码。我认为你没有设置所有财产。
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.mail.yahoo.com");
props.put("mail.stmp.user", "username");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.password", "password");
Session session = Session.getDefaultInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
String username = "username";
String password = "password";
return new PasswordAuthentication("username", "password");
}
});

25雅虎门不再响应。使用587:
props.put("mail.smtp.port", "587");
完整代码:
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.mail.yahoo.com");
props.put("mail.stmp.user", "username");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.password", "password");
Session session = Session.getDefaultInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
String username = "username";
String password = "password";
return new PasswordAuthentication("username", "password");
}
});
