setup email connection in java

Question

I am trying to make connection to the email server using property files and session store value. and all the parameters are given dynamically. this is what i'm trying

  Properties props = System.getProperties();
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.host", emailHost);
  props.put("mail.smtp.port", "2525");
  Session sessions = Session.getDefaultInstance(props);
  Store store = sessions.getStore(emailAccType);
  store.connect(emailHost, emailId, emailPwd);

Even if i am giving the correct email and password, the connection is not setting up.

please do the needful help.

Thanks in advance.

Answer 1

Couple of ideas:

1. make sure the email server does not require pop3 login first.
2. make sure port is open in firewall

Do you get any exceptions during your tries?

Answer 2

Does it throw an exception or it just doesn't work? I am using gmail for sending emails and I used something like this:

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