        if (recipients.indexOf(',') > 0) {
            message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
        } else {
            message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));
        }


        Transport.send(message);

    }

}

NB: for proper working of this code include mail.jar in library and make sure that the antivirus and firewall of your system is off..Otherwise an Exception named SSLHandShakeException will arise.
