Java Mail Class

Question

Hello,

I am looking for a Java class that will allow me to send emails without the need for SMTP. Like the PHP mail() class that uses sendmail.

Any suggestions?

Many Thanks

James

Before Using this Program, you need to have Javasoft's JavaMail class files which can be downloaded from here http://www.javasoft.com/products/javamail/index.html

You will also need the JavaBeansTM Activation Framework extension or JAF (javax.activation). It is available at http://java.sun.com/beans/glasgow/jaf.html.

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
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", "smtp.jcom.net");

    // 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);
}

All mail senders will need an SMTP server to transfer their mail. The nice thing about PHP mail is that you don’t need to configure it (it use the sendmail binary directly, if sendmail is not installed, PHP mail will not work either).

If all you want is building a Java application that can send out e-mail without configuring an SMTP server for that, you could use a Java based SMTP server, for example:
