This code shows the error of:

Could anyone help me, why can't it convert socket to TLS. What can I do to resolve the error?? Please do help.

By default, Gmail does not allow "less-secure" Apps to access your email.
In order to get your code to run:
Sign into your gmail account in a browser.
Go to https://www.google.com/settings/security/lesssecureapps
Set the Access for less secure apps option to Turn on

Either the certificate has not been installed in file cacerts or you might want to set the google smtp url as "trusted". try add this code
properties.put("mail.smtp.ssl.trust", "smtp.gmail.com");
on the other note. You might need to set the javax.mail.Authenticator when you try to get the session

// Build session to create MimeMessage to send
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.gmail.com");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.ssl.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "587");
props.setProperty("mail.smtp.quitwait", "false");
Session session = Session.getDefaultInstance(props, new Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("name_here", "password_here");
}
});

JavaMail Messaging Exception

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)

at javax.mail.Service.connect(Service.java:366)
at emailSend.main(emailSend.java:29)
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);}

if you have no smtp server on your machine then download it and run after downloading.
try this
I was Using old version of mail.jar use this jar mail-1.4.7.jar and after that for authentication To open Account Access : https://www.google.com/settings/security/lesssecureapps (turn on) this was the problem if using google smtp

I am trying to send an e-mail from a Gmail account to a Gmail accout without success. I need to do this for my business e-mail to send out newsletters ect.
EDIT:
I changed a section of code to this:
Properties properties = new Properties();
properties.put("mail.smtp.host", "smtp.gmail.com");
properties.put("mail.smtp.port", "25");
properties.put("mail.smtp.auth", "true"); //make it true
properties.put("mail.smtp.starttls.enable", "true"); //make it true
properties.put("mail.smtp.ssl.trust", "smtp.gmail.com");
//Authentication is needed use your gmail user and password"smtp.gmail.com"
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("email#gmail.com", "password");
}
};
Session session = Session.getInstance(properties, auth);
And now I get the exception:
javax.mail.AuthenticationFailedException
I think that the problem is that your properties are contradictory.
You are setting the SMTP port to 587, which (according to this page) is the server port for SMTP over TLS. But then you are setting mail.smtp.starttls.enable to false.
Naturally the Google SMTP server is confused ... and it tells you that it was expecting the client to send a STARTTLS command.
Solutions:
Change the mail.smtp.starttls.enable property to true.
Alternatively, change the mail.smtp.port property to 465 (the SSL port)
You don't have the option of using "vanilla" SMTP ... which is a good thing if you care about securing your email traffic.
According to this resource, you also need to enable authentication. (The page has extensive Java example code ...)
The response code 530 means access denied
The accompanying message indicates that gmail is expecting a STARTTLS.
Try with
props.put("mail.smtp.starttls.enable", "true");
Although it may need more properties to work properly
Besides: non-secure SMTP is always a bad idea unless its local.
starttls should be true.
means add :
props.put("mail.smtp.starttls.enable", "true");
then post me that working or not ?
Do it like this
Properties properties = new Properties();
properties.put("mail.smtp.host", "smtp.gmail.com");
properties.put("mail.smtp.port", "465");
properties.put("mail.smtp.auth", "true"); //make it true
properties.put("mail.smtp.starttls.enable", "true"); //make it true
properties.put("mail.smtp.ssl.trust", "smtp.gmail.com");
//Authentication is needed use your gmail user and password"smtp.gmail.com"
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("yourGmailUserName", "yourGmailpassword");
}
};
Session session = Session.getInstance(properties, auth);

Error when sending mail in Java

i have desktop application and i face this error when sending mail javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is: java.net.ConnectException: Connection refused: connect
~code~
String host="smtp.mail.yahoo.com";
Properties props = new Properties();
props.setProperty("mail.smtp.auth", "true");
props.setProperty("mail.smtp.host",host);
props.put("mail.smtp.host", host);
props.put("mail.stmp.user", "abc#yahoo.ca");//User name
//To use TLS
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.password", "mypassword"); //Password
props.put("mail.smtp.socketFactory.fallback", "false");
Session session1 = Session.getDefaultInstance(props, new Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
String username = "abc#yahoo.ca";
String password = "mypassword";
return new PasswordAuthentication(username, password);
}
});
MimeMessage msg = new MimeMessage(session1);
String from = "abc#yahoo.ca";
String subject = "Testing...";
msg.setFrom(new InternetAddress(from));
msg.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(email));
msg.setSubject(subject);
Transport.send(msg);
YahooMail smtp port is 465 or 587
Add this :-
props.put("mail.smtp.port", "465");
or
props.put("mail.smtp.port", "587");

Error while sending mails using smtp

I need to send mail from my gmail account to another. I used the following code.
String fromaddress = "xxx#gmail.com";
String password = "yyy";
String hostname = "smtp.gmail.com";
String hoststring = "mail.smtp.host";
String toaddress = "yyy#gmail.com";
String emailcontent;
Properties properties = System.getProperties();
properties.setProperty(hoststring, hostname);
Session session = Session.getDefaultInstance(properties);
try{
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(fromaddress));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(toaddress));
message.setSubject("hi");
emailcontent = "hi...";
message.setText(emailcontent);
System.out.println(emailcontent);
Transport.send(message);
System.out.println("Sent....");
}catch (MessagingException mex)
{
mex.printStackTrace();
}
But i get the error as follows...
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25
How am i to solve this. Can you please help me out.
public static void sendEmail(Email mail) {
String host = "smtp.gmail.com";
String from = "YOUR_GMAIL_ID";
String pass = "YOUR_GMAIL_PASSWORD";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true"); // added this line
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);

// Set Subject: header field
message.setSubject("SUBJECT");
// set content and define type
message.setContent("CONTENT", "text/html; charset=utf-8");
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
} catch (MessagingException mex) {
System.out.println(mex.getLocalizedMessage());
}
}
}`
I think this should do the trick.
I think you need to change the port no. 25 to 587
you can get help from
http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/
gmail setting help link:
http://gmailsmtpsettings.com/
Just adding few more tweaks to the question above:
Change the port to 465 to enable ssl sending.
I don't think above code will work, as you need to have an authenticator object too. As smtp also requires authentication in case of gmail.
You can do something like:
Have a boolean flag,
boolean authEnable = true; //True for gmail
boolean useSSL = true; //For gmail
//Getters and setters for the same
if (isUseSSL()) {
properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.put("mail.smtp.socketFactory.port", "465");
}
Authenticator authenticator = new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("abc#gmail.com", "xyz"));
}
};
if (isAuthEnable()) {
properties.put("mail.smtp.auth", "true");
session = Session.getDefaultInstance(properties, authenticator);
} else {
session = Session.getDefaultInstance(properties);
}
