Hi!

Many thanks. I have tried sending to a gmail account and a hotmail account and it works.
Now, i have another question related. What should i do if i want to send an email in a particular day. I have thought doing with listeners but i don´t know how. If anyone knows...please tell me, many thanks.

This is the code of sending mails which works:

String  d_email = "[e-mail]",
            d_password = "xxxxxx",
            d_host = "smtp.gmail.com",
            d_port  = "465",
            m_to = "[e-mail]",
            m_subject = "Testing";
           
           
    public String button1_action() {
       
       
         String m_text = textArea1.getValue().toString();
        Properties props = new Properties();
        props.put("mail.smtp.user", d_email);
        props.put("mail.smtp.host", d_host);
        props.put("mail.smtp.port", d_port);
        props.put("mail.smtp.starttls.enable","true");
        props.put("mail.smtp.auth", "true");
        //props.put("mail.smtp.debug", "true");
        props.put("mail.smtp.socketFactory.port", d_port);
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.socketFactory.fallback", "false");
       
        SecurityManager security = System.getSecurityManager();
       
        try {
            Authenticator auth = new SMTPAuthenticator();
            Session session = Session.getInstance(props, auth);
            //session.setDebug(true);
           
            MimeMessage msg = new MimeMessage(session);
            msg.setText(m_text);
            msg.setSubject(m_subject);
            msg.setFrom(new InternetAddress(d_email));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
            Transport.send(msg);
        } catch (Exception mex) {
            mex.printStackTrace();
        }
        return null;
       
       
    }
    private class SMTPAuthenticator extends javax.mail.Authenticator {
        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(d_email, d_password);
        }
    }
