“Exception reading response” error trying to send mail in java

Question

Here is a little code to send email from java.

public static void sendMail(){
    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.host", "mail.domain.tld");
    props.put("mail.smtp.debug", "true");
            Session session = Session.getInstance(props,
      new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("sender@domain.tdl", "pwd");
        }
      });
    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("sender@domain.tdl"));
        message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse("receiver@yahoo.fr"));
        message.setSubject("Testing Subject");
        message.setContent("This is a test <b>HOWTO<b>", "text/html; charset=ISO-8859-1");
        Transport.send(message);
        System.out.println("Done");
    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }
}

But running it I have this error

Exception in thread "main" java.lang.RuntimeException: javax.mail.MessagingException: Exception reading response;
  nested exception is:
    java.net.SocketException: Software caused connection abort: recv failed
    at Test.main(Test.java:112)

I don't understand the reason of the error because this code worked for me in the past. Here is the jars I'm using:

• dsn-1.6.0
• gimap-1.6.0
• imap-1.6.0
• javax.mail-1.6.0
• javax.mail-api-1.6.0
• logging-mailhandler-1.6.0
• mailapi-1.6.0
• pop3-1.6.0
• smtp-1.6.0

After modification asked by @Bill, here is the new error I have

Exception in thread "main" java.lang.RuntimeException: javax.mail.MessagingException: Could not connect to SMTP host: mail.hereka.org, port: 25;
  nested exception is:

But if I remove the ssl property this is the new error

Thanks

Answer 1

This is not related to the jar but more a SMTP server error. you could try using

telnet mail.domain.tld

and try connecting to the host. I suggest you include a port like

props.put("mail.smtp.port", "portnumber");

you can try the standard port 25 (unsecure) or 587 (secure) instead.
