Invio email automatico

[Ivan86]

Ciao,
ho seguito un tutorial per l'invio di una mail in automatico.
In pratica voglio che al click di un button venga inviata una mail di conferma.
Non riesco a inviare la mail e mi da warning.
Ho importato le seguenti librerie:
mail.jar
activation.jar
additionnal.jar

Questo il mio codice:

private class InviaEmailTask extends AsyncTask<Void,Void,Void>  {
        @Override
            protected Void doInBackground(Void... params) {

                        Mail m = new Mail("info@miodominio.it", "miaPsw"); 
                        String[] toArr          = {aaa@gmail.com};
                        
                        m.setTo(toArr); 
                        m.setFrom("info@miodominio.it"); 
                        m.setSubject("iscrizione"); 
                        m.setBody("corpo email"); 
                 
                try {
                       m.send();
                       pd.dismiss();
                       Toast.makeText(IscrizioneActivity.this, "Iscrizione avvenuta con successo", Toast.LENGTH_SHORT).show();
                       finish();
               } catch (Exception e1) {
                      e1.printStackTrace();
        }

Questa la classe Mail:

public class Mail extends javax.mail.Authenticator {
        private String _user;
        private String _pass;

        private String[] _to;
        private String _from;

        private String _port;
        private String _sport;

        private String _host;

        private String _subject;
        private String _body;

        private boolean _auth;

        private boolean _debuggable;

        private Multipart _multipart;

        public Mail() {
                _host = "smtp.miodominio.it"; // default smtp server
                _port = "25"; // default smtp port
                _sport = "465"; // default socketfactory port

                _user = ""; // username
                _pass = ""; // password
                _from = ""; // email sent from
                _subject = ""; // email subject
                _body = ""; // email body

                _debuggable = false; // debug mode on or off - default off
                _auth = true; // smtp authentication - default on

                _multipart = new MimeMultipart();

                // There is something wrong with MailCap, javamail can not find a
                // handler for the multipart/mixed part, so this bit needs to be added.
                MailcapCommandMap mc = (MailcapCommandMap) CommandMap
                                .getDefaultCommandMap();
                mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
                mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
                mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
                mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
                mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
                CommandMap.setDefaultCommandMap(mc);
        }

        public Mail(String user, String pass) {
                this();

                _user = user;
                _pass = pass;
        }

        public boolean send() throws Exception {
                Properties props = _setProperties();

                if (!_user.equals("") && !_pass.equals("") && _to.length > 0
                                && !_from.equals("") && !_subject.equals("")
                                && !_body.equals("")) {
                        Session session = Session.getInstance(props, this);

                        MimeMessage msg = new MimeMessage(session);

                        msg.setFrom(new InternetAddress(_from));

                        InternetAddress[] addressTo = new InternetAddress[_to.length];
                        for (int i = 0; i < _to.length; i++) {
                                addressTo[i] = new InternetAddress(_to[i]);
                        }
                        msg.setRecipients(MimeMessage.RecipientType.TO, addressTo);

                        msg.setSubject(_subject);
                        msg.setSentDate(new Date());

                        // setup message body
                        BodyPart messageBodyPart = new MimeBodyPart();
                        messageBodyPart.setText(_body);
                        _multipart.addBodyPart(messageBodyPart);

                        // Put parts in message
                        msg.setContent(_multipart);

                        // send email
                        Transport.send(msg);

                        return true;
                } else {
                        return false;
                }
        }

        public void addAttachment(String filename) throws Exception {
                BodyPart messageBodyPart = new MimeBodyPart();
                DataSource source = new FileDataSource(filename);
                messageBodyPart.setDataHandler(new DataHandler(source));
                messageBodyPart.setFileName(filename);

                _multipart.addBodyPart(messageBodyPart);
        }

        @Override
        public PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(_user, _pass);
        }

        private Properties _setProperties() {
                Properties props = new Properties();

                props.put("mail.smtp.host", _host);

                if (_debuggable) {
                        props.put("mail.debug", "true");
                }

                if (_auth) {
                        props.put("mail.smtp.auth", "true");
                }

                props.put("mail.smtp.port", _port);
                props.put("mail.smtp.socketFactory.port", _sport);
                props.put("mail.smtp.socketFactory.class",
                                "javax.net.ssl.SSLSocketFactory");
                props.put("mail.smtp.socketFactory.fallback", "false");

                return props;
        }

        // the getters and setters
        public String getBody() {
                return _body;
        }

        public void setBody(String _body) {
                this._body = _body;
        }

        public String[] getTo() {
                return _to;
        }

        public void setTo(String[] toArr) {
                this._to = toArr;
        }

        public String getFrom() {
                return _from;
        }

        public void setFrom(String string) {
                this._from = string;
        }

        public String getSubject() {
                return _subject;
        }

        public void setSubject(String string) {
                this._subject = string;
        }

e infine questo è il warning che non mi permette di inviare la mail:

Mi rispondo da solo

Usando un dominio aruba devo usare necessariamente:
host: smtps.aruba.it
port: 465
