Hi,

I got an error on sending the mail. Its worked in local system. Error
coming in the line

Transport t = ses1.getTransport("smtp");

Code:
=====

public String sendMail(String To, String subject, String
message , String from){
String result="";
try{
String host="mail.myfamilymeet.com";
String[] to= {To};

String filename="";
String username = "user";
String password = "pwd";
Properties prop = new Properties();
prop.put("mail.smtp.port", "25");
prop.put("mail.smtp.host",host);
prop.put("mail.transport.protocol", "smtp");
prop.put("mail.smtp.starttls.enable","true");
prop.put("mail.smtp.auth", "true");
Authenticator auth = new SMTPAuthenticator();
//Authenticator auth = new MyAuthenticator();
Session ses1=Session.getDefaultInstance(prop, auth);
//Session ses1=Session.getInstance(prop,null);
ses1.setDebug(false);
Message msg=new MimeMessage(ses1);

msg.setFrom(new InternetAddress(from));
msg.setSubject(subject);
BodyPart msgbp=new MimeBodyPart();
msgbp.setContent(message,"text/html");
Multipart mpart=new MimeMultipart();
if(filename.length()>0){
msgbp=new MimeBodyPart();
DataSource src=new FileDataSource(filename);
msgbp.setDataHandler(new DataHandler(src));
msgbp.setFileName(filename);
}
mpart.addBodyPart(msgbp);
msg.setContent(mpart);
InternetAddress[] addressTo = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++) {
addressTo[i] = new InternetAddress(to[i]);
}

msg.addRecipients(Message.RecipientType.TO, addressTo);
msg.saveChanges();
Transport t = ses1.getTransport("smtp");
t.connect(host, username, password);
t.sendMessage(msg, msg.getAllRecipients());
t.close();
result="Mail Sent Succefully";
}
catch(Exception es){
es.printStackTrace();
result=es.toString()+"<br><b>Exeption is: </b>";
StackTraceElement[] exe= es.getStackTrace();
int count=0;
while(count<exe.length){
result=result+"<br>"+exe[count];
count++;
}
}
return result;
}
private class SMTPAuthenticator extends javax.mail.Authenticator {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("user", "pwd");
}
}
