mail using java from iitb network

[Manish Punjabi]

I am able to use gmail smtp server to send emai [using java mail] from external network. However, within iit network, I am trying to use smpt-auth.iitb.ac.in and it fails to send mails.

 The following is the code.

final String username = "ldapid";

final String password = "ldappasswd";

 

Properties props = new Properties();

props.put("mail.smtp.host", "smtp-auth.iitb.ac.in");

props.put("mail.smtp.port", "25");

props.put("mail.smtp.ehlo", "true");

props.put("mail.smtp.starttls.enable", "true");

props.put("mail.smtp.ehlo", "true");

props.put("mail.smtp.auth", "true");

        props.put("mail.debug", "true");

 

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("lda...@iitb.ac.in"));

message.setRecipients(Message.RecipientType.TO,

InternetAddress.parse("rece...@gmail.com"));

message.setSubject("Testing Mail");

message.setText("test email !");

 

Transport.send(message);

 

} catch (MessagingException e) {

throw new RuntimeException(e);

}

}

I get the following exception:

Exception in thread "main" java.lang.RuntimeException: javax.mail.MessagingException: Can't send command to SMTP host;

  nested exception is:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Check how to accept certificates from SMTP server.

You might want to change the auth_type.

smtp.esmtp_features["auth"] = "LOGIN PLAIN"

There should be a java equivalent for this

@Saket : I tried login plain but still the same exception.

@DIlawar: I tried this http://nodsw.com/blog/leeland/2006/12/06-no-more-unable-find-valid-certification-path-requested-target but I get an exception
