i want to send email from java from an unsecured address
i use in smtp
I get a login error, and you could not access the address because it is not secure
I added permission to unsecure sites, but it didn't help
I can't add a security certificate on the computer,
because the code ends up being run from another server,
and not from my computer
I have to bypass the insecure site issue only through the code
my code is:
package test;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.net.ssl.SSLContext;
import org.ini4j.IniPreferences;
import java.io.FileReader;
import java.security.cert.X509Certificate;
import java.util.Properties;
import java.util.prefs.Preferences;
import com.sun.mail.util.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
public class TestMailAuth {
public static void main(String[] args) {
String emailtext = "blabla";
String mailserver= "142.90.x.xx";
String mailPort = "25";
String emailFrom = "xxxxxx.co.il";
String emailTo = "xxxxxx.co.il";
String pass="xxxxxxxxx"
Authenticator authenticator = new Authenticator()
{
//@Override
final String smtpAuthUserName =emailFrom;
final String smtpAuthPassword = pass;
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(smtpAuthUserName, smtpAuthPassword);
}
};
Properties properties = new Properties();
try {
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
properties.put("mail.smtp.host", mailserver);
properties.put("mail.smtp.port", mailPort);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.ssl.trust", "*");
properties.put("mail.smtp.ssl.socketFactory", sf);
}
catch (Exception e) {
System.out.println(e);
}
properties.put("mail.debug", "true");
Session session = Session.getInstance( properties, authenticator );
try
{
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(emailFrom));
InternetAddress[] to = {new InternetAddress(emailTo)};
message.setRecipients(Message.RecipientType.TO, to);
message.setSubject("test_SUBJECT");
message.setText(emailtext);
Transport.send(message);
System.out.println("end. Success");
}
catch (MessagingException exception)
{
exception.printStackTrace();
}
}
}
my eror:
javax.mail.MessagingException: Can't send command to SMTP host;
nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I added debug and this is the result:

I searched a lot of guides, some said to try to change to:
properties.put("mail.smtp.starttls.enable", "false");
but i get eror :
