I am sending mail through gmail coount using port 465.
I am sending mail in loop.(reciients are present in a list)
I am able to send first mail succesfully , but as soon as second mail shoots
I get error unalbe to connect smtp.gmail.com at 465.
enter code hereprops.put("mail.smtp.host", smtp_host);
props.put("mail.smtp.port", smtp_port);
props.put("mail.smtp.user", smtp_user);
props.put("mail.smtp.auth", AUTH);
props.put("mail.smtp.starttls.enable", STARTTLS);
props.put("mail.smtp.debug", DEBUG);
props.put("mail.smtp.socketFactory.port", smtp_port);
props.put("mail.smtp.socketFactory.class", socket_factory));
props.put("mail.smtp.socketFactory.fallback", "false");
try {
//Obtain the default mail session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(true);
//Construct the mail message
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setRecipient(Message.RecipientType.CC, new InternetAddress(cc));
message.setSubject(subject);
message.setContent(messageText, "text/html");
message.setHeader("Content-Type" , "text/html" );
message.saveChanges();
//Use Transport to deliver the message
Transport transport = session.getTransport("smtp");
transport.connect(HOST, USER, PASSWORD);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
} catch (Exception e) {
e.printStackTrace();
}
Use Port 587 for TLS/STARTTLS. And following properties only if you use TLS/STARTTLS
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
And if you are trying to connect through SSL. Try only this -
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
...
Session session = Session.getDefaultInstance(props, null);
Change this with -
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username#gmail.com", "password");
}
});

I have written the above code for sending email using javamail API through SMTP but I ended up with the following exception. Please see my code below. I have used debugging mode and below the code you can find the exception as well.
Error Details

I wrote a program to send gmails using JavaMail API. Following is my code:
import java.util.*;
import javax.mail.*;
import javax.activation.*;
import javax.mail.internet.*;
import javax.mail.Session;
import javax.mail.Transport;
class emailSend{
public static void main(String[] args) {
String recipient = "receiver#gmail.com";
String sender = "sender#gmail.com";
String host = "smtp.gmail.com";
Properties props = System.getProperties();
props.put("mail.smtp.host",host);
props.put("mail.smtp.user", sender);
props.put("mail.smtp.password", "password");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props);
try
{
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(sender));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(recipient));
message.setSubject("This is the subject");
message.setText("This the message");
Transport transport = session.getTransport("smtp");
transport.connect("smtp.gmail.com",465,"sender01#gmail.com", "password");
transport.sendMessage(message, message.getAllRecipients());
System.out.println("Mail successfully sent");
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
But I'm getting following error:
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:2197)

I tried disabling the firewall, but it was of no use.
What should I do?
Add properties:
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.ssl.checkserveridentity", "true");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.debug", "true");
props.put("mail.smtp.EnableSSL.enable", "true");
props.put("mail.smtp.socketFactory.fallback", "false");
You need to configure your Gmail account security to allow it to send emails from your app check the link
This is my working code
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
//get Session
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication( from, password);
}
});
//compose message
try {
MimeMessage message = new MimeMessage(session);
message.addRecipient(Message.RecipientType.TO,new InternetAddress(recepient));
message.setSubject(subject);
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(msg, "text/html");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
Transport.send(message);
} catch (MessagingException e) {throw new RuntimeException(e);}
Using my home computer I am able to send an email through Gmail without error, however, when I try to run the same code on my Linux box It throws:

}
}
I am using Oracle JDK 181 on both systems.
I am able to successfully connect "telnet smtp.gmail.com 465" on the Linux box
After switching to TLS it works
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.ssl.trust", "smtp.gmail.com");
I try to send mail using below code but I am getting Exception like.
javax.mail.AuthenticationFailedException

Please any one help me how can I solve it.
Here is my code.Thanks
String mailBODY = "<h3>Hi this is my test Mail</h3>;
final String username = "username#gmail.com";
final String password = "password";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props, new GMailAuthenticator(username, password));
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("TEST"));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(test#gmail.com));
message.setSubject("Mail subject test");
message.setContent(mailBODY,"text/html; charset=utf-8");
Transport.send(message);
System.out.println("mail has been send");
} catch (MessagingException e) {
e.printStackTrace();
}
Try adding props and sending like this:
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
// ...
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
// ...
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
I got this error after I enabled 2-step verification on my google account
I've got gmail and yahoo working, but not hotmail. Here's what I have, what am I doing wrong?
private String mailhost = "smtp.live.com";
public hotmailSenderActivity(String user, String password) {
this.user = user;
this.password = password;
//This connects to the actual mailserver
Security.addProvider(new com.provider.JSSEProvider());
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", mailhost);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.socketFactory.port", "587");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("smtp.starttls.enable", "true");
props.put("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.quitwait", "false");
session = Session.getDefaultInstance(props, this);
I have tried port 25 + 587 without the SSL stuff. I have tried port 465 WITH the SSL stuff. The email and password are correct (Ive hard coded them to be sure).
I don't receive any errors... So whats the problem?
1) use debug output:
session.setDebug(true);
2) hotmail smtp server starts non-ssl connection on port 25 or 587, and uses starttls after initial connection; thus remove lines
props.put("mail.smtp.socketFactory.port", "587");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
3) mimimum amount of settings is then:
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.live.com");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
this assumes port is 25, otherwise add props.put("mail.smtp.port", "587");
4) yet even nicer looks this:
...
props.put("mail.smtp.starttls.enable", "true");
Session session = Session.getDefaultInstance(props);
Transport trans = session.getTransport("smtp");
trans.connect("smtp.live.com", 25, "user", "pass");
now you're connected, use methods of Transport

Get rid of all that socket factory stuff, you don't need it.
