Answer 1

thanks Alan
but i think there is some other problem because same code is
working when i am using in windows as well as i am using authentication method
also but it is not working when running in Solaris Environment
here is the code i am using to send the mail
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.mycompany.com");//smtp protocol for IIBF
props.put("mail.smtp.starttls.enable","true");//setting start TLS to be true
props.put("mail.smtp.auth", "true");// authentication is false
props.put("mail.smtp.port", port);//setting the port number it can be either 25 or 587
props.put("mail.smtp.username", "noreply");
props.put("mail.smtp.password","noreply");
props.put("mail.debug", "true");
Authenticator auth = new SMTPAuthenticator();
Session session1 = Session.getDefaultInstance(props);
java.util.Properties sessionProperties = new java.util.Properties();
sessionProperties.put("mail.smtp.auth", "true");
message.setFrom(new javax.mail.internet.InternetAddress(From ,"name"));
message.addRecipient(javax.mail.Message.RecipientType.TO, new javax.mail.internet.InternetAddress(To));
message.setText(TextCo);
message.setSubject(subject);
message.setContent(boyd, "text/plain");
message.reply(true);
Transport trans = session1.getTransport("smtp");
trans.connect(SMTP_HOST_NAME, SMTP_AUTH_USER, SMTP_AUTH_PWD);
boolean ddd = trans.isConnected();
message.saveChanges();
trans.sendMessage(message, message.getAllRecipients());
above code is working properly in windows but not in Solaris
plz guide what next to do
thankx in advance
