Java EE (Java Enterprise Edition) General Discussion

Hello,

I'm experiencing the following issue when I try to authenticate to the SMTP server of a customer of mine from my java app:

While I can connect to the server via telnet:

Many others customers of mine are running the same app without any problem. Here is the code I'm using to send emails:

Properties props = new Properties();
props.put("mail.smtp.host","out.alice.it");
props.put("mail.smtp.auth", "true");
Session session = Session.getInstance(props, new MyAuthenticator(username, password));
SMTPTransport t = (SMTPTransport)session.getTransport("smtp");
try {
t.connect("out.alice.it", username, password);
t.sendMessage(msg, msg.getAllRecipients());
} catch (Exception e){
e.printStackTrace();
} finally {
t.close();
}

...
...

class MyAuthenticator extends Authenticator{
private String userName, passWord;

public MyAuthenticator(String user, String passwd){
super();
userName = user;
passWord = passwd;
}

public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, passWord);
}
}


I've also analyzed the net traffic with WireShark analyzer and I saw the SMTP server responded to my java app with a TCP packet with the RST flag set after sending the base64 encoded user name.

Any clue?
Thanks in advance
