Oto kod:

 

final String username = "**raft.pl";
final String PATH_FILE = "C:\test.txt";
        final String password = "XXX";

        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "false");
        props.put("mail.smtp.host", "mail***craft.pl");
        props.put("mail.smtp.port", "587");

        Session session = Session.getInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username, password);
                    }
                });

        String msgBody;

        if(name == null)
            msgBody = "NoName";
         else msgBody = "XXX";

        try {
            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress("***aft.pl", "kl - sender"));
            msg.addRecipient(Message.RecipientType.TO,
                    new InternetAddress("&&&l.com", "&&&"));
            msg.setSubject("Pliki z emailem");


            MimeBodyPart attachFilePart = new MimeBodyPart();
            FileDataSource fds = new FileDataSource(PATH_FILE);
            attachFilePart.setDataHandler(new DataHandler(fds));
            attachFilePart.setFileName(fds.getName());




            Multipart mp = new MimeMultipart();
           
            mp.addBodyPart(attachFilePart);
           
            msg.setContent(mp);

            Transport.send(msg);


        } catch (AddressException e) {
        // ...
        e.printStackTrace();
    } catch (MessagingException e) {
        // ...
        e.printStackTrace();
    } catch (Exception e){
        e.printStackTrace();
    }
    }

Ktoś wie jak to naprawić? Używam JavaMail
