Must issue a STARTTLS command first. Sending email with Java and Google Apps
- by Sergio del Amo
I am trying to use Bill the Lizard's code to send an email using Google Apps. I am getting this error:
Exception in thread "main" javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: 530 5.7.0 Must issue a STARTTLS command first. f3sm9277120nfh.74
at javax.mail.Transport.send0(Transport.java:219)
at javax.mail.Transport.send(Transport.java:81)
at SendMailUsingAuthentication.postMail(SendMailUsingAuthentication.java:81)
at SendMailUsingAuthentication.main(SendMailUsingAuthentication.java:44)
Bill's code contains the next line, which seems related to the error:
props.put("mail.smtp.starttls.enable","true");
However, it does not help.
These are my import statements:
import java.util.Properties;
import javax.mail.Authenticator;
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;
Does anyone know about this error?
