        public static void send(String from, String to,
                                String subject, String content)
                throws AddressException, MessagingException {
 
	Properties props=new Properties();
 
        props.put("smtp.domainName.com","domainName");
 
	Session   session1  =  Session.getDefaultInstance(props,null);
 
	Message msg =new MimeMessage(session1);
	msg.setFrom(new InternetAddress(from));
 
      	msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to,false));
 
           msg.setSubject(subject);
 
           msg.setContent(content,"text/html");        
 
           Transport.send(msg);            
 
        }
}

This code was working well on my dedicated server but know I am working on VPS.
My server provided said the previously it was open smtp but now there is username and password for smtp server.
How can I set username/password that I have in the above mentioned code?

Any help will be highly appreciated

The OS=CentOS Enterprise Linux 5.x

Thanks & best regards
