What were the exact steps that you did?
 
The link you supplied has a number of example values. If you didn’t substitute values that fit your system, it won’t work. We need to see your actual steps.
 
 Also, the link assumes that you already understand the Mail Server Framework and doesn’t mention it. Did you have the Mail Server Framework running?

If you think you settings are correct based on what Tom suggested then it’s something else. Another possibility is if the e-mails subject / sender / or domain name is getting stopped/blocked by a spam filter. We had a situation here where the e-mail subject was “Automail” and was not reaching a majority of our recipients. Was this a test to an internal e-mail account or was it a live run to the outside world? Did it affect all or just some users?

Thanx for your response.Here we don’t have the Mail Server Framework, we are hosted Mail Server in Third party vendor

we are hosted Mail Server in Third party vendor
 
That’s common.
 
Here we don’t have the Mail Server Framework,…
 
Then you can’t use SNDDST to send internet e-mail.
 
But you shouldn’t be using SNDDST at all for e-mail anyway. You should use the SMTP services that come with the system. SNDDST doesn’t do SMTP e-mail — it must be processed by the system to get routed over to your SMTP server. In order for that to happen, you have do all of the steps in the article that you linked, and the Mail Server Framework runs to make those steps work.
 
Have you worked out an agreement with your hosted mail server provider to let your AS/400 pass e-mail through them? Do you know if they have changed their configuration to enable it?
