Check SMTP server status

[sandeep.ctg]

Hello all,

i have a java program to send emails working fine. But now before sending a email i want to ensure that my mail-server is up and running. So how do i get the smtp server status. That should be platform independent:confused::confused:

Did you read JavaMail API?

You don't want to actually send the email, you can open a TCP socket to port number 25 of your mail server and send the separate commands to subject, mail from/to. Something like this,

TestMail your_domain.com
From: youre_mail@your_domain.com
To: recipient@recipient_domain.com

And then check each response. If you didn't get any error, means that your mail server is working fine.

Actually i want to send email using JavaMail API but before that i just want to have a method which returns true/false depending on the smtp server status.

You can send mail as 2 step process.

1. step - connect to server
2. step - send message

On first step:
"Usually, when you get a low level SocketException when connecting, the problem is due to your networking configuration. Usually it's not a Java problem." (from JavaMail API FAQ)

So don't use ordinary
Transaport.send ()

try different connection problems scenarios and use something like this:

 Transport t = session.getTransport(protocol);
    try {
        t.connect(username, password);
   }    catch(SocketException e){
}
 
try {

t.sendMessage(msg, msg.getAllRecipients()

} catch(Exception e) {}

and be sure u use

session.setDebug(true); // Verbose!

in your code when performing this tests!

Did you try what I've suggest to you? Using that you can build a method as you want to see in your code. Give a try and see.
