How to send mail using JavaMail API?

[Jyothsna Panchagnula]

Hi all ,

I am a newbie to Java Mail API , and I am trying to send mail using Java mail API from home and I have an internet connection:-

   
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 test {

	public static void main(String[] args)
	{
		test t= new test();
		String[] recipients = {"***@gmail.com",&quot***@yahoo.co.in"};
		String message="You have been successfully registered with company";
		
		try {
			t.postMail(recipients, "Company Registration Information", message, "info@*****.com");
		} catch (MessagingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}


public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException
{
    boolean debug = false;

     //Set the host smtp address
     Properties props = new Properties();
     
     props.put("mail.smtp.host", "whattopuhere");
     

    // create some properties and get the default Session
    Session session = Session.getDefaultInstance(props, null);
    session.setDebug(debug);

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

    // set the from and to address
    InternetAddress addressFrom = new InternetAddress(from);
    msg.setFrom(addressFrom);

    InternetAddress[] addressTo = new InternetAddress[recipients.length]; 
    for (int i = 0; i < recipients.length; i++)
    {
        addressTo[i] = new InternetAddress(recipients[i]);
    }
    msg.setRecipients(Message.RecipientType.TO, addressTo);
   

    // Optional : You can also set your custom headers in the Email if you Want
    msg.addHeader("MyHeaderName", "myHeaderValue");

    // Setting the Subject and Content Type
    msg.setSubject(subject);
    msg.setContent(message, "text/plain");
    Transport.send(msg);
}

}

I am not getting what to put for "SMTP" server host address.

any inputs on this will be highly appreciated.

thanks,
Jyothsna

Contact your ISP.

That's the host name or address of the mail server you intend to use. You can use the one you use for your personal mail (in which case you'll need to add authentication code for sending username and password) or run a server on your own machine. Apache James is an example of a server that's pretty easy to get up and running.
