SMTPSVC: unable to bind to the destination server in DNS
Posted on 2006-04-05
I am getting the following error message in my system log whenever i try to send out emails from my web server:
Event id: 4000
Details: Message delivery to the remote domain 'XXX' failed for the following reason: Unable to bind to the destination server in DNS.
My web server is windows 2000 server, IIS 5.0 and no exchange server is installed. There are 3 network cards installed on the server. Request is received from another computer(NT4) to send out emails using SMTP. Previously there were no problems to send out emails, now the emails remain in the Queue folder and does not go out.
The server is able to access the internet eg. yahoo, but sending emails to yahoo accounts failed. Attempts to ping and telnet also failed. IIS has been re-installed to no avail. I have tried to set Smart Host(solution recommended by support.microsoft) but that didnt work too.
This is an urgent problem, hence the high award of points.
