Thanks for the link but unfortunately this link only works when I get the NDR.
Smtp protocol error is only with one domain that is brain.net.pk all mails stuck in the queue and when you take the properties of that below it shows you smtp protocol error. I used telnet on port 25 works well. This is an old issue I am facing. I discuss the issue with the brain.net.pk guys and they told me that they were having this problem but now it is solved. I have another smpt server connected to the internet and am forwarding all brain.net.pk mails from my exchange 2000 server to this smtp server, from there mails of brain.net.pk going fine. I don't know where the problem is, my exchange 2000 server is connected on leased line(all mails going fine except brain.net.pk). While the backup smtp server connected via dialup with other isp. Any suggestion / hint will be appreciated.
