Sending mail

[Gaios Augustus]

Hey all,

I am making password recovery module for my software where I need send user data through user mail.

My code is:

import java.sql.Connection;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class MailRecovery {

    public void MailRecovery(Connection conn, String recoveryMail, String recoveryPassword, String recoveryUsername) {

        final String username = "********@gmail.com";
        final String password = "******";

        Properties props = new Properties();
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

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

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("******@gmail.com"));
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(recoveryMail));
            message.setSubject("*** - Password Recovery");
            message.setText("Username: " + recoveryUsername
                    + "\n Password: " + recoveryPassword);

            Transport.send(message);

            PopError CALError = new PopError();
            CALError.infoBox("Podaci su poslani na mail!", "Success!");

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

The problem is that I am getting this mail from google (google 2-step verification is  disabled):

Someone just used your password to try to sign in to your account from a non-Google app. Google blocked them, but you should check what happened. Review your account activity to make sure that no one else has access.

Is there anything I can do about it or I have to find other way to send mail?

Solution:

1.) Login into gmail account over Your web browser

2.) Go to this link: https://www.google.com/settings/security/lesssecureapps

3.) Click "Turn on"

Thanks for reporting the solution - it is certainly not obvious.
