How to send mail using JAVA Mail.

[Sandeep Sontakke]

Hi,

I have created on feed back from to send a mail .
I used by gmail id to recieve a mail .
but it wont work bcause in both the field of gmail i.e. From and To I m geting my email id.
here is the code that I have used.


public void postMail() throws MessagingException
  {
    boolean debug = false;

     //Set the host smtp address
     Properties props = new Properties();
     props.put("mail.smtp.host", "imap.gmail.com");
     props.put("mail.smtp.starttls.enable","true");
     props.put("mail.smtp.auth", "true");
  
    
     //props.put("mail.smtp.port", "993");
     

    Authenticator auth = new SMTPAuthenticator();
    Session session = Session.getDefaultInstance(props, auth);

    session.setDebug(debug);

    // create a message
    Message msg = new MimeMessage(session);

    // set the from and to address
   

    InternetAddress[] addressTo = new InternetAddress[2];
    /*for (int i = 0; i < recipients.length; i++)
    {
        addressTo[i] = new InternetAddress(recipients[i]);
    }*/
    addressTo[0] = new InternetAddress("sandeep....@gmail.com");
    addressTo[1] = new InternetAddress(email);
    msg.setRecipients(Message.RecipientType.TO, addressTo);
   
    message = "Hello.......";

    // Setting the Subject and Content Type
    msg.setSubject("Thanks For feed Back");
    msg.setContent("Test Mail ", "text/plain");
    msg.setFrom(new InternetAddress(email));
    Transport.send(msg);
    System.out.println(addressTo[0]+"Mail Sent successfully...11");
   
 
 }
And one Inner Class
private class SMTPAuthenticator extends javax.mail.Authenticator
{

    public PasswordAuthentication getPasswordAuthentication()
    {
        String username = "sandeep....@gmail.com";
        String password = "XXXXXX";
        return new PasswordAuthentication(username, password);
    }
}

}

Thanks & Regards

Hi Sreehari,

     Test Driven Developement is a defineltly a good way for
executing projects.
But i think if you have a reasonable good team of dedicated testing
team then the writing the test cases and the development goes on
parallel. Brainstorming sessions do happen initially with the entire
team before the test cases are written or the development team starts
writing the Program specs so that there is a clear understanding of
the requirement.
The Test cases are reviewed so that they are meeting the requirements.
    When developemnt team gives the release the test cases are
executed.

So writing test cases and then starting the developemnt is not a
feasible task.

Kiran

but it wont work bcause in both the field of gmail i.e. From and To I m geting my email id.

here is the code that I have used</sandeep>

 

<Rejin>Is it working for diff id, suppose the sending mail id is urs and the recving is someone else. </Rejin>

 

[Rejin Chandran]

I think it hangs some where while sending. So set a time out value as i shown below

 props.put("mail.smtp.connectiontimeout",timeOutVal);

Then you will get exact error.

 

Thanks and Regards

One can configure Gmail in outlook as well as Thunderbird.

The advantage is you Request for Receipt which usually gmail/Yahoo does not provide.

Further backup of mail you have on your machine.
