使用 Javamail API 从 yahoo id 向其他电子邮件 id 发送邮件
我无法使用 Java 邮件 API 从我的 yahoo id 发送电子邮件.我尝试了谷歌的不同选项，但失败了.请看看我下面的代码，如果我遗漏了什么，请告诉我.在我看来 Yahoo 不提供免费发送邮件的服务，但我不确定.请提供您对此的看法.
I am not able to send email from my yahoo id using Java mail API. I tried different options from Google,but fails. Please have a look my below code and let me know if I am missing something. In my point of view Yahoo does not provide the free service to send mails, but I am not sure. Please provide your thoughts on this.
import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
public class MailExample {
private static final String SMTP_HOST_NAME = "smtp.mail.yahoo.com";
private static final int SMTP_HOST_PORT = 587;//465,587,25
private static final String SMTP_AUTH_USER = "dummyrls@yahoo.com";
private static final String SMTP_AUTH_PWD = "my password";
public static void main(String[] args) throws Exception{
new MailExample().test();
}
public void test() throws Exception{
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "true");
// props.put("mail.smtps.quitwait", "false");
Session mailSession = Session.getDefaultInstance(props);
mailSession.setDebug(true);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Testing SMTP-SSL");
message.setContent("This is a test", "text/plain");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("rlss@abc.com"));
transport.connect
(SMTP_HOST_NAME, SMTP_HOST_PORT, SMTP_AUTH_USER, SMTP_AUTH_PWD);
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}
}
上面的代码在 Gmail 上运行良好，但在 Yahoo 上却出现如下错误:
The above code works fine for Gmail, but for Yahoo it's giving error like:

我该如何解决这个问题?
How can I solve this?
推荐答案
试试这个代码
public class SendMail {
String host, port, emailid,username, password;
Properties props = System.getProperties();
Session l_session = null;
public BSendMail() {
host = "smtp.mail.yahoo.com";
port = "587";
emailid = "a@yahoo.com";
username = "a";
password = "pwd";
emailSettings();
createSession();
sendMessage("a@yahoo.com", "rahul@gmail.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);
// props.put("mail.smtp.socketFactory.port", port);
// props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
// props.put("mail.smtp.socketFactory.fallback", "false");
}
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) {
//System.out.println("Inside sendMessage 2 :: >> ");
try {
//System.out.println("Sending Message *********************************** ");
MimeMessage message = new MimeMessage(l_session);
emailid = emailFromUser;
//System.out.println("mail id in property ============= >>>>>>>>>>>>>> " + emailid);
//message.setFrom(new InternetAddress(emailid));
message.setFrom(new InternetAddress(this.emailid));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
message.addRecipient(Message.RecipientType.BCC, new InternetAddress(AppConstants.fromEmail));
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;
}
}
