Hi Lyallex, for everybody that is still struggling with this issue, here is a base \
non-authentication email class.  Once you get this working start adding the special \
features you need.   This worked with my hosting provider (Kattare) who were \
absolutely worthless in providing any guidance, after much testing.

import java.util.Date;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


public class Email{
    String  d_email, d_password, d_host, d_port;
    
    public Email(String email, String password, String host, String port) {
        d_email = email;
        d_password = password;
        d_host = host;
        d_port  = port;
    }
    
    public boolean send(String m_to, String m_subject, String m_text) {
        // email address
        String to = m_to;
        String from = d_email;
        //  ISP mail server
        String host = d_host;
        // 
        Properties props = new Properties();
        // static transport.send() - need to specify which host to send it to
        props.put("mail.smtp.host", host);
        // To see what is going on
        props.put("mail.debug", "false");
        //
        Session session = Session.getInstance(props);
        try {
            // message
            Message msg = new MimeMessage(session);
            //message attributes
            msg.setFrom(new InternetAddress(from));
            InternetAddress[] address = {new InternetAddress(to)};
            msg.setRecipients(Message.RecipientType.TO, address);
            msg.setSubject(m_subject);
            msg.setSentDate(new Date());
            // message content
            msg.setText(m_text);        
            //send
            Transport.send(msg);
            return true;
        }
        catch (MessagingException mex) {
            // 
            mex.printStackTrace();
            return false;
        }
    }
 }
 
Happy holidays

Don
