Send mail problem having invalid address with correct addresses

Question

I used java mail api to send mails. the code is a s below
javax.mail.Session mailSession=(javax.mail.Session)ctx.lookup("java:/Mail");
mailSession.setDebug(false);
javax.mail.Message msg = new javax.mail.internet.MimeMessage(mailSession);
msg.addRecipients(javax.mail.Message.RecipientType.TO, addressToArr);
msg.setSubject(mailSubject);
msg.setContent(mailBody, contentType);
javax.mail.Transport.send(msg);
But if there is an invalid address in the recipient address array, the email won't be sent to the correct addresses as well. i just want to know whther it happens any coding issues or our mail server implementation.

Hi!
You need to activated properties config mail.smtp.sendpartial to true :
// Setup partial mail
props.put("mail.smtp.sendpartial", (new Boolean(partial)).toString());
if the recipient address array have bad address, it will still be sent to good address...
or/and check email address before send mail :
public static boolean isValidEmail(String email)
          if (email == null) return false;
          boolean valid = true;
          try
               InternetAddress addr = new InternetAddress(email);
               addr.validate();
          catch (AddressException ex)
               valid = false;
          return valid;
}regards,
