session.setDebug(debug);
Message msg = new MimeMessage(session);
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);

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



method call:
==========
new MyMailer().sendSSLMessage(sendTo, emailSubjectTxt,emailMsgTxt, emailFromAddress);



Note : mail.jar is needed. Change your SMTP settings according to your needs. I have tried with Gmail.

email validation in Java using apache.commons-validator

Validating the mail very effectively, is little difficult. Here is a simple code for validating your email in Java. It is using the apache.commons-validator.jar and oro-gump-18012007.jar.

// Code email validation

public static boolean validateEmailAddress(String sEmail){
       EmailValidator emailValidator = EmailValidator.getInstance();
       return emailValidator.isValid(sEmail);
}

Commons validator, validates true for '%$^^%$$@$%$#.com'. Don't get affraid, '%$^^%$$@$%$#.com' is a correct email id according to http://en.wikipedia.org/wiki/E-mail_address.
