public class Mailklasa {
public static void main (String args[]) throws Exception {
String host = "out.mail.bih.net.ba";
String from = "asimv@bih.net.ba";

// Get system properties

// Setup mail server
props.put("out.mail.bih.net.ba", host);


// Get session
Session session = Session.getDefaultInstance(props, null);

// Define message
MimeMessage message = new MimeMessage(session);

// Set the from address
message.setFrom(new InternetAddress(from));

// Set the to address
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));

// Set the subject
message.setSubject("Hello JavaMail");

// Set the content
message.setText("Welcome to JavaMail");

// Send message
Transport.send(message);
