Sending mail from local host

Question

hi, i am running my application in tomcat.
if i specify a smtp host server name , could able to send a mail in same domain without using authenticator.
But i want to know without specifying a smtp server name, is it posstion to send email using "localhost" as the server.
Properties props = new Properties();
props.put("mail.transport.protocol", "smtps");
props.put("mail.smtp.host", smtpHost);
Session session = Session.getDefaultInstance( props);
MimeMessage message = new MimeMessage( session );
message.setFrom( new InternetAddress(aFromEmailAddr) );
message.addRecipient(
Message.RecipientType.TO, new InternetAddress(aToEmailAddr)
message.setSubject( aSubject );
Multipart multipart = new MimeMultipart();
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(aBody);
multipart.addBodyPart(messageBodyPart);
MimeBodyPart attachmentBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filePath);
attachmentBodyPart.setDataHandler(new DataHandler(source));
attachmentBodyPart.setFileName(fileName);
multipart.addBodyPart(attachmentBodyPart);
message.setContent(multipart);
Transport.send( message );
In my code if i mention a smtp server name in smtpHost , code is working fine, but i want to use localhost.
so what will be the code for that??? should i have to configure anything.
plz help.
thnx in advance

The code for sending mail from localhost is simply this:
props.put("mail.smtp.host", "localhost"); But this will not work unless you have an SMTP server running on the same computer where that code is running. That's what "localhost" means. If you are trying to send e-mail without using a server which knows who you are, stop trying to do that. That makes you a spammer. Don't do it.
