In this article, we will show you how to send an email via Gmail SMTP server.
To send email in Java, we need JavaMail
pom.xml
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>
1. Gmail SMTP via TLS
SMTP = smtp.gmail.com
Port = 587
SendEmailTLS.java
package com.mkyong;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class SendEmailTLS {
public static void main(String[] args) {
final String username = "[email protected]";
final String password = "password";
Properties prop = new Properties();
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "587");
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtp.starttls.enable", "true"); //TLS
Session session = Session.getInstance(prop,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(
Message.RecipientType.TO,
InternetAddress.parse("[email protected], [email protected]")
);
message.setSubject("Testing Gmail TLS");
message.setText("Dear Mail Crawler,"
+ "\n\n Please do not spam my email!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
2. Gmail via SSL
2.1 The logic is the same, just pass in different properties values.
SMTP = smtp.gmail.com
Port = 465
SendEmailSSL.java
package com.mkyong;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class SendEmailSSL {
public static void main(String[] args) {
final String username = "[email protected]";
final String password = "password";
Properties prop = new Properties();
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "465");
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtp.socketFactory.port", "465");
prop.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
Session session = Session.getInstance(prop,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(
Message.RecipientType.TO,
InternetAddress.parse("[email protected], [email protected]")
);
message.setSubject("Testing Gmail SSL");
message.setText("Dear Mail Crawler,"
+ "\n\n Please do not spam my email!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
3. Application-specific password required
3.1 If 2-Step verification is ON. We will hits the following error message :
Caused by: javax.mail.AuthenticationFailedException: 534-5.7.9 Application-specific password required. Learn more at

3.2 To fix it, follow this guide to create an App Password
URL : https://support.google.com/accounts/answer/185833?p=InvalidSecondFactor
URL : https://myaccount.google.com/security
No difference in code, just puts the newly generated app password instead.
SendEmail.java
package com.mkyong;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class SendEmail {
public static void main(String[] args) {
final String username = "[email protected]";
final String password = "puts your app password here"; // update here
// same code...
}
}
java.net.UnknownHostException: smtp.gmail.com
Make sure firewall or proxy server didn’t block this
Make sure firewall or proxy server didn’t block this
smtp.gmail.com
I tried using TLS but it is giving me authentication error.

Thanks mkyong bro it worked
I am getting following error
javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
I met this bug please help me!

Wow thank you!!!

Thank you very much!
I got email from Google says: February 15, 2021 – Access to LSAs will be turned off for all G Suite accounts.
I have to turn on LSA, and then connect Gmail SMTP server smtp.gmail.com for sending email from JAVA program using JavaMail.
Question: will this Google’s change make “connect Gmail SMTP server smtp.gmail.com using JavaMail” impossible? and we hav eto change to use Gmail API for just send an email? Thanks!
I used your code in for a test. I have the dependency in the pom.xml, so I ran it from Intellij IDE, it worked well. But after I created the jar file, then all the dependency classes were not included inside the jar file. It did not happen to the other dependencies. Do you have any idea why the dependency classes not included?
thank you,
Is there any way with which I will not be required to save the password in the backend? Or at least make it more secure if not remove it from the code?
Still works on 2020-May-25. I had to create the application password to get connected. If you haven’t made the application password yet and you are having trouble, check your application email [whatever account is attached to the ‘username’ getting passed into new PasswordAuthentication()], you might have a polite email from google that you might be getting hacking attempts with instructions on how to make the application password. You may need to turn on two-factor authentication to be able to generate one.
Hope this helps!
On Avast configuration Mail Shield disabling “Scan Outbound emails (SMTP)” , allowed me to have It working.
thanks for your code
Can you please tell how to add attachments also in mail(with code) in sendmailSSL
thanks for your code

Hi mkyong,
I get error javax.mail.MassagingException: can’t find local email address.
Please give suggestions for this ASAP.
this is working for me thank you so much.
Thanks a lot Mkyong 🙂 ..Solution for “Caused by: javax.mail.AuthenticationFailedException: 534-5.7.9 Application-specific password required.” works for me.
When I deploy it project to sever it produces the following message “The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.”. why? and how i can solve the problem even though i implement SpringBootServletInitializer in Main class.
It was exactly what I needed. Thank you so much!
I get the following error here: Transport.send(message);

—–> how to fix it
The TLS connection worked like a charm for a long time for me, but now I got a javax.mail.MessagingException: 530 5.7.0 Must issue a STARTTLS command first.
The solution was to add props.put(“mail.smtp.EnableSSL.enable”, “true”);
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587;
nested exception is:
java.net.ConnectException: Connection timed out: connect
i don’t know why..
Hi…I have java SE, Where may I download javaee.jar and mail.jar? Also the package com.mkyong.common… Thanks a lot..Wald
Here how can We check invalid email address([email protected]) before Transport.send(message); I am facing this issue in my production application. Can you give me some idea!
There is solution.
Head over to Account Security Settings (https://www.google.com/settings/security/lesssecureapps) and enable “Access for less secure apps”, this allows you to use the google smtp for clients other than the official ones.
It worked for me!
Thanks!
After reducing security level
i am able to authenticate
Nice one
I used both version – via TLS and via SSL. Both don’t work!
I am getting this kind of error please help on that

I want to send a file and not a message how u can help me plz ???
Take a look at this link for sending files: http://www.tutorialspoint.com/java/java_sending_email.htm
i’m sending automatic email from my app but i need two jars: mailapi.jar and smtp.jar My question is are these jar files really necessary? Here is my code (actually working):
try {
Properties props = System.getProperties();
props.put(“mail.transport.protocol”,”smtp”);
props.put(“mail.smtp.starttls.enable”,”false”);
props.put(“mail.smtp.host”,host);
props.put(“mail.smtp.auth”,”true”);
props.put(“mail.smtp.user”,userid);
props.put(“mail.smtp.password”,password);
props.put(“mail.smtp.from”,userid);
Session session = Session.getInstance(props, new SMTPAuthenticator(props));
MimeMessage message = new MimeMessage(session);
InternetAddress fromAddress = null;
InternetAddress toAddress = null;
try {
fromAddress = new InternetAddress(from);
toAddress = new InternetAddress(to);
} catch (AddressException e) {
e.printStackTrace();
}
message.setFrom(fromAddress);
message.setRecipient(RecipientType.TO, toAddress);
message.setSubject(subject);
message.setText(text);
message.setSentDate(new Date());
// SMTPSSLTransport transport
// =(SMTPSSLTransport)session.getTransport(“smtps”);
Transport transport = session.getTransport(“smtp”);
transport.connect(host, userid, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
} catch (MessagingException e) {
e.printStackTrace();
}
SMTPAuthenticator on the Session session line is underlined in red by eclipse. Any ideas why? Not an import issue
i was facing the same problem solve it by just trying another email address
and its work fine…….
Thanks A lot .Worked Well
Thank you very much! It is really working and it is well explained! Thanks again and keep up the good work!
It’s works. Thanks you!

Hello, I have tried your example in SSL mode. Thank you for the example I always try your examples for my leaning. But I had to disable my Avast Antivirus Mail Shield.

Hi, I need to send a mail using outlook, does it work too?
Thank you.It really works. You Are Great Man!!!
Why do people insist on doing this by hand?? Just use something like Simple Java Mail, a thin API on top of the javax.mail API, which does this for you:
https://code.google.com/p/simple-java-mail/
smtp: new Mailer(“smtp.host.com”, 25, “username”, “password”)
smtps: new Mailer(“smtp.host.com”, 25, “username”, “password”, TransportStrategy.SMTP_SSL)
smtps tls: new Mailer(“smtp.host.com”, 25, “username”, “password”, TransportStrategy.SMTP_TLS)
The Project moved: https://github.com/bbottema/simple-java-mail
Now includes Builder Pattern, custom header, custom properties, custom Session.

It means the port 587 is disabled in your systems. Check with system administrator to enable that port.

In this, since you are using SMTP server protocol, this can be broken at the network layer when we will be using it in an application. Then how can me make it secure?
Any suggestions?
This is one of the few examples online that actually works, with a good explanation.
Also, +1 for providing an SSL implementation! Great job.
hello
if I want to send multiple emails to different users simultaneously, are feasible these options?, because I see creates a new instance for each mail, which would make very slow execution of a program
bye.
thanks man….great job…keep it up..
Working great.Thanks.
Gmail refuses to send mails again if the created account is new assuming it is a spam account. Using the old account will work.Thanks again.

Try typing ping smtp.gmail.com in a command window and see if you can reach it. If the ping doesn’t respond something is blocking your connection.
Hello,
thanks for giving the example, it works for me.
But I need to know, if I want to send an email from outlook instead of gmail yahoo then how to do that.
Can anybody tell me with clear example.
Thanks in advance

What is recommended to use? TLs or SSL
SSL for secured access, TLS for normal purpose.
Thank you very much for your posting.
Really helpful
I just wanted to thank you for the great example. I have been trying to figure this out for awhile now. This was a really big help. ^_^

Try to telnet the smtp host.
telnet smtp.gmail.com 465
and see if it’s getting connected from your network. Most probably,this will not work in VPN.
Thanks mkyong for this code.
I am connected to telnet smtp.host.com 465 still i am getting error like that please help as soon as possible thanks….
getting the same Exception, help? :/
try “mail.host” instead of “smtp.mail.host”
Add
props.put(“mail.smtp.ssl.trust”, “*”);
To run this example required only one library – mail.jar.
Thanks for the post!
Great code snippets! Thanks for sharing!

Hello to all my brother.pls i’m new to restful web service and also new in using the new apache TomeePlus .My aim of using restful webservice is to integrate it in my web e-comerce websit.
FIRST:
My IDE is Netbeans 7.3.1,
In my sql ,I built a database called oko which is made up on table with ID,firstname and Lastname, this is just for testing purposes.
in My netbeans i built a web app called AGAIN
in thsi AGAIN I built entity beans from my Mysql database,”entity class = Oko.java”
i built restful web service from entity class “Oko.java”;
i used glassfish server 3.2.
when i tested the restful webservice it work pretty well.
i was very happy with this !!.
SECOND :
Now i tried to do thesame thing with my apache TomeePlus server ,
but it is not working .
i included “mysql driver jar file ” to TomeePlus /lib,
i Fololwed the step on FIRST:
it gave me an error which has kept me one week trying to resolve.

i need your help and support pleas.
You can also contact me via E-mail :[email protected]
THANKS FOR YOUR HELP!!
Your example works prefect! Thank you very much!
I already wrote a wrapper class where I just pass source email and password and a sendTo() method with destination mail, subject and message arguments. Also added possibility to choose between TLS and SSL. This is all done based on your example, thank you very much!
fantastic code, works very fine, remember all to add mail.jar to your classpath!
Maybe it’s just old but doesn’t seem to work at all with either of them just error messages.

I think you have a firewall problem, are you sure port 587 is open for outside connection? Otherwise, first try with a mail client like Thunderbird and test whether it works or not (basically it’s the same).
Try using port number 465 for smtp connection. If you are using SSL connection use port number 465 and if TSL use port number 587

I am using a Win 8 machine, java version 1.7.0.17 and java mail 1.4.7
Can you please help
Thanks for neat solution.But
1. Authorization credential should be used for authentication than how come form field “message.setFrom(new InternetAddress(“[email protected]”));” be different from authentication credentials?Even I kept different credentials in form and authentication,but mail is still sent to the one I mentioned in authentication.What I am missing?
2.If I am to send a mail with no-reply option,how this can be done?
Thanks alot mkyong code works fine…..:)
Its work fine.. thanks alot Mkyong. Thank you very much
It works fine and thanks alot…
Hi
I am really thankful to you for posting this. This is wonderful. However, I have a question.
For SSL, if we use props.put(“mail.smtp.port”, “465”); under a proxy it doesn’t work. Instead, if we use props.put(“mail.smtp.port”, “25”); i.e using port 25 it works fine. What is the difference between these two port numbers and how does proxy affects it?
Thank you.
I have found the problem.
The dependency for javax.mail needs to be the first in the maven build file. I am using spring and scheduler (using a previous example of MKYONG) and somehow these are interfering with the javax.mail dependency.
All working fine now.
hello Sir How do I configure JavaMail to work through my proxy server?
i had configured Java Network Connection in Control Panel, but i doesn’t work. can you help me Sir?

Hi I am using
Front End : RAD(Rational Application Development-IBM Tool)
Back End: DB2 (IBM Tool)
So which code should I use TLS or SSL?
What are the prerequisites I need to install to run both the code.
and whether we need saparate smtp server,or any smtp protocol?
Provide me download link and give me some necessary guidance.
Thank you

package com.mkyong.common;
package sendEmail;
I am trying to implement this to automatically send emails on a predetermined schedule.
ignore the “com.mkyong.common”, it’s just packaging in my development environment, not require to run above mailing program.
thank you
plz tell me how to code login page that only auntheticate gmail uname and password and redirect other page in struts2
Great Work Mkyong.
Cheers! =)
Hey Sir,
Thanks a lot for your tutorial and your great website in general!
I tried this code, but got an error:
Could not connect to SMTP host: smtp.gmail.com, port: 465;
The error appears in the both examples (with SSL and TLS).
Can you help me please?
Sorry, that was my fault. I used the older version of mail.jar library.
Everything works perfectly)
Thanks one more time!
Hello Sir,
The codes are running successfully for Gmail vis SSL ; however on button click, the event is being fired twice; that two similar email are being sent,
can you explain this please?
Dear friend,
I have implemented the GMail via SSL in my project.
The form contains a button to send notification automatically to members once directly clicking on the “SEND NOTIF” button;
Your codes run successfully(thank you loads for that) but the problem is that the mail is being sent twice. I will be very grateful if you can help me to find the reason behind this.
I Found some Issue in the code when i’m trying to send to a particular mail id for more than 3 to 4 times , its gives a error “com.sun.mail.smtp.SMTPAddressFailedException: 554 5.7.1 ” although the id is correct and even when the mail id is not proper it doesn’t give any error.
Any thing to highlight for this issue.

Always create package from specific tasks. so here u want to send automated mails. so create a mailer class which sends a mail. test it explicitly then integrate in ur servlet code. here you created main in EmailSendDB class. that is wrong. create a mail which send a mail and except arguments like sender name, receiver name and subject and body. do not call main in servlet. this is wrong. modify ur EmailSendDB.
I wrote on mailer service class which have mathod send mail. you can use that.
call it like
MailerService mail = new MailerService(); //cc & bcc are comma separated mail.sendMail("sender email id", "send to", "cc", "bcc", "first mail", "hi, this is my first mail ");//you can leave black which fields you are not using.find it here http://morwalz.com/java-mail/

Hello Sir. I implemented to send email using SSL connection over Gmail smtp server. when i give a valid receiver email-id everything works perfectly. But when i give an invalid receiver email-id it doesn’t show any exception like invalid emailid. This invalid emailid notification is sent to the sender’s email account. But i don’t get any MessagingException on my screen. Here is the code. Please help me out. Thanks in advance.
public class SendEmail
{
public static int sendEmail(String toAddress,String userID)
{
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”);
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(“[email protected]”,”password”);
}
});
try
{
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(“senderaddress”));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(toAddress));
message.setSentDate(new Date());
message.setSubject(“Account Activation for T20home”);
message.setContent(“Hello”,”text/html”);
Transport.send(message);
}
catch(MessagingException mex)
{
Exception ex=mex;
if (ex instanceof SendFailedException)
{
SendFailedException sfex = (SendFailedException)ex;
Address []invalid= sfex.getInvalidAddresses();
if(invalid!=null)
{
return -1;
}
Address []valid_sent=sfex.getValidSentAddresses();
if(valid_sent!=null)
{
return 1;
}
Address []valid_unsent=sfex.getValidUnsentAddresses();
if(valid_unsent!=null)
{
return 0;
}
}
}
}
}
That is the nature of Email. It is not possible to check for a valid receiver because the mail may be sent through many servers to eventually get to the receiving server, possibly some hours later depending on traffic.
Only the receiving server can decide whether the email address is finally valid, and the only way it can inform you is by sending an email.
It’s exactly the same if you use any email program .
So, how do the websites handle this junk data with invalid email-ids. They shouldn’t be kept in the database permanently ??
Before clalling sendEmail method. validate email address by writing your own method. Email will not validate the data.
Hi Mkyong,
Thanks very much for posting these code examples. Having working examples greating accelerates learning the JavaMail API.
One note: In my experience I only needed
, not
. I downloaded the JavaMail-1.4.5 bundle from Oracle and that was the only jar necessary to get both of these examples working: http://www.oracle.com/technetwork/java/index-138643.html
Thanks for your input, may be javaee.jar in your classpath already, this is standard j2ee jdk jar.
Hi,
Am trying to send the mail using ssl, but it has stucked on transport.send(message). I am not getting any error and it remain same for a long time. The method for sending mail, am using in servlet. But before using in servlet,I have tested with java compiler. It is working fine
Kindly provide the help.

Greetings,
Thanks for this very useful code that works perfect.
I just would like to ask you if you can post the same code, but with file attachment.
Thanks a lot

hey did you find the way of attaching the file?
i did, yes 🙂
Do you need my code ?
yes i do need it
import java.util.*;

// its not mine. but mixed codes from two programs . it finely works.
// called the method from a servlet.

// Set To: header field of the header.
message.addRecipient(Message.RecipientType.TO,

// Set Subject: header field
message.setSubject(“This is the Subject Line!”);
// Create the message part

Thanks a lot. It worked like charm.
Great Work
Thanks and Warm Regards,

if your code is correct , email id and password is also correct.
and your getting google authentication exceptition.
then open gmail using web browser enter username & password
then gmail will ask for word verification. after word verfication you will login into account.
then run you java code…no google authentication exceptition will come
Thanks, this code works fine
Hi all,
and thanks for the hints.
However, I have a little problem;
I’m trying example ‘JavaMail – GMail via TLS’
and I can say it basically ‘works’.
However, what I am finding, and perhaps I misunderstand the goal here, is that gmail hijacks my ‘from’ field.
My goal, or intention, is to simply use gmail as a smtp relay, to send on email from my own email server, which existing on a dynamic IP range, has troubles being accepted out there in the spam jittery world.
The actual wanted results being that email sent on, be identified as having come from :
[email protected]
and not,
@gmail.com
Yet, this is what happens.
Any ideas? What are others experience?
Oh, and I forgot to mention;
I have tried almost the exact same thing with my own ISP smtp server, and things come out as hoped/expected.
/* TLS also need authentication,you have to give authentication in your session value */
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 SendMailTLS { public static void main(String[] args) { String host = "smtp.gmail.com"; int port = 587; String username = "username"; String password = "password"; Properties props = new Properties(); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); Session session = Session.getInstance(props,new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication("username","password"); } }); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress("[email protected]")); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]")); message.setSubject("Testing Subject"); message.setText("Dear Mail Crawler," + "\n\n No spam to my email, please!"); Transport transport = session.getTransport("smtp"); transport.connect(host,port,username, password); Transport.send(message); System.out.println("Done"); } catch (MessagingException e) { throw new RuntimeException(e); } } }Your program is giving javax.mail.MessagingException: Could not convert socket to TLS;
please hint for solve it.
thanks in Advance.
SSL worked but the TLS sample failed with this:
Exception in thread “main” java.lang.RuntimeException: javax.mail.AuthenticationFailedException: failed to connect, no password specified?
The password is specified but no joy. Pls advise. Thanks.
The original code is badly written. When the Transport.send is being called the authentication might still not be completed, that’s probably why you got the error. One should add ConnectionListener to the transport object and then call Transport.send when the connection is fully opened which means putting the call inside the ‘opened’ event handler of the ConnectionListener object.
Transport transport = session.getTransport("smtp"); transport.addConnectionListener(new ConnectionListener() { @Override public void closed(ConnectionEvent e) { } @Override public void disconnected(ConnectionEvent e) { } @Override public void opened(ConnectionEvent e) { try { Transport.send(message); } catch (MessagingException ex) { ex.printStackTrace(); } } }); transport.connect(host, port, username, password);Well, I must correct myself. I tried both, the original version and mine. Neither works. However, I found extremely strange that it worked for other users here. Javadoc API for Transport.send says:
“Note that send is a static method that creates and manages its own connection. Any connection associated with any Transport instance used to invoke this method is ignored and not used.”
So, transport.connect(host, port, username, password) is actually irrelevant and is not used at all during the invocation of Transport.send. Having in mind that, I managed to construct the following working version:
package blah.blah; 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 TLSGmail { public static void send(final String username, final String password, String sender, String destination, String subject, String messageText) { Properties props = new Properties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.transport.protocol", "smtp"); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.port", "587"); Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress(sender)); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(destination)); message.setSubject(subject); message.setText(messageText); Transport.send(message); System.out.println("Done"); } catch (MessagingException e) { throw new RuntimeException(e); } } }I tried using the script it says no password specified… which username and passowr dis it pertaining to? where do we register? tnx
Help a lot
Thank you !!
I have the same exception as you. I tested this piece of code at home and it worlkd OK. Then I tried it at my work place and I got the exception (ping also times out).
So I guess it may have something to do with the internal proxies or conf features oin my company’s intranet. Checking with my IT services.
Any help will be welcome.
thanks, i’ve been looking for this in a lot of sites, and your code is the only, that i found that works!
sir i cannot add multiple recipients in sendmailtls as said by comment(in program).whenever i separate them by cooma i get an error
Amit,
First, you’re an idiot…
Second, post the actual error you’re whining about!
Third, read the JavaDoc…

message.addRecipient(RecipientType.TO, new InternetAddress(“[email protected]”));
message.addRecipient(RecipientType.TO, new InternetAddress(“[email protected]”));

Mail sending is working superb.
But do you know , how can we check whether the mail sent is successful or failed?
I would appritiate if ur SSL code works for connecting other smtp too.
I am trying to connect 10.5.128.146 at port 25.
but it is not connecting. Connection timed out msg is coming.
plz help
Thanks in Advance
The problem is that TCP/25 the normal , un-crypted port is. So it depends on your SMTP-server-config if it allows encrypted connection or if you have to use plain connection.
This problem does not come from the code but rather from your server-config.
Well … now … I found the problem with TSL Method.
Your code works as follows
-setting up a new Transport-Connection
-connecting the Transport-Object
so far so good
but then your code goes wrong
-using the static method Transport.send(Message)
The Doc says : this method handles its OWN connection
So why this is the reason for failure ?
Because there no information in the Properties wich Username nor wich Password to use. So to fix this there two ways:
1) setting up the properties correct and delete the whole manual connection set-up
2) using SMTPTransport.sendMessage(Message, Address[]) to send the message
and finaly clean up the connection by invoking CLOSE()
to use the 2nd method you need to set-up a SMTPTransport or a SMTPSSLTransport with properties wich contains the TSL information and then invoke Service.connect(String, int, String, String)
a working example with TSL
// simplyfied package-imports import java.util.*; import javax.mail.*; import javax.mail.internet.*; public class SendMailTLS { // simplyfied Exception-handling by simple throwing public static void main(String[] args) throws Exception { // setting up connection parameters String host="smtp.gmail.com"; int port=587; String user="username"; String pass="password"; // setting up security properties Properties props=new Properties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); // setting up connection to SMTP-Server and connect Session session=Session.getInstance(props); Transport transport=session.getTransport("smtp"); transport.connect(host, port, user, pass); // building Address-Array with recipients // for more than one address seperate them by simple comma Address[] addresses=InternetAddress.parse("[email protected]"); // setting up new MimeMessage Message message=new MimeMessage(session); // setting the FROM-Header wich should equal to username message.setFrom(new InternetAddress(user)); // setting the TO-Headder // CC and BCC must set with seperate setRecipents() calls message.setRecipients(Message.RecipientType.TO, addresses); // setting subject message.setSubject("TEST SUBJECT"); // constructing text/plain body of mail // for text/html mail ask google =D message.setText("text/plain BODY"); // sending message with connected Transport transport.sendMessage(message, addresses); // printing status if success System.out.println("SEND"); // closing Transport-connection clean transport.close(); } }hope this helps
Thanks sir ,now its work properly.
finaly
got it work with the other SMTP-Server web.de
simply used TLS-version with changes as i said …
addition
please add comment that G-Mail only works on Port 465 for SSL Method !!
Sorry … hit RETURN to fast … my bad
what i want to say :
SSL works fine with G-Mail … but not with some other Servers … tried 465 and 587 as port value …
error :
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
Server : web.de *germany*
TLS doesnt work at all
always get this
javax.mail.AuthenticationFailedException: failed to connect, no password specified?
i am Java-Programmer for 6 years now … and i know what these exceptions mean … but i dont know WHY they are thrown …
any ideas ?
found a solution for TLS-Method
simply use the SSL-Class
BUT
-remove the SSL-Factory-Settings
-set Port to 587
-add the StartTLS-line from TLS-Class to it
DONE
the TLS-Method seems to have bugs in the connect()-Method
Hello sir,i went to send mail in my email id with help of java.mail,for this code use by me is following

That is: I want send mail from any address mail to a static address mail using stmp. How can I code? Thanks!
Addition…
That’s: Any Address From Email has not
Authentication but it can send mail. Please help me!
You need to code it yourself, and tell me what’s your problem. Not asking others to do it for you.
Hi mkyong
I had code as:
Properties props = new Properties();
props.put(“mail.smtp.host”, “mailserver.com”);
Session s = Session.getInstance(props,null);
InternetAddress from = new InternetAddress(dynamic_email);// get customer input
InternetAddress to = new InternetAddress([email protected]”); //this’s my email
MimeMessage message = new MimeMessage(s);
message.setFrom(from);
message.addRecipient(Message.RecipientTy
pe.TO, to);
message.setSubject(“Your subject”);
message.setText(“Your text”);
Transport.send(message);
But it is not send mail, Please help me! thanks so much!
Please post your last caused by error message
Error: authentication require.
Now I want receive mail from any client will send for me, my account email is Gmail. How should I code for the correct?
Hi mkyong
I have been coding as:
import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class SendMailTLS { public void receiveMailFromClient(String mailclient, String subject, String content) { String host = "smtp.gmail.com"; int port = 587; String username = "[email protected]"; String password = "123456"; Properties props = new Properties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); Session session = Session.getInstance(props); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress(mailclient)); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]")); message.setSubject(subject); message.setText(content); ); Transport transport = session.getTransport("smtp"); transport.connect(host, port, username, password); Transport.send(message); System.out.println("Done"); } catch (MessagingException e) { throw new RuntimeException(e); } } }Now I call method above: receiveMailFromClient(“[email protected]”,”Hello Mydream”,”How are you?”);
But I had not been received mail from any client sent for me. Can you help

HI,
i am also got same exception.
could you find out the reason of that exception.
how did u solve that problem?
please give reply to me.
thanks,
Your program cannot find the smtp.gmail.com host. You should configure DNS servers or use some DNS server configuration property in JavaMail.
Gmail TLS didn’t work for me. It gave me authentication failed exception as mention by yehia. So I added pass Anonymous instance of javgax.mail.Authenticator class as shown below.
Session session = Session.getInstance(props,new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username,
password);
}
});
It did resolved the issue but not I am getting SendFailureException as shown below:
