Hi, all
I am posting my concern about sending email through smtp service
I have windows 2000 server with smtp service and without exchange. In ASP
code, I am emailing using smtp object. It has been working a several months.
However I got the folloing message recently.

message from event viewer :
"Message delivery to the remote domain 'empal.com' failed for the following
reason : An internal DNS error caused a failure to find the remote server"

The server where smtp service is on has DNS setting not of internal DNS
server but of public DNS server for its name resolution.
Do you have any idea why this message appear?

Thanks a lot in advance

Can you resolve the MX record of the destination from your server,
using NSLookup? Have you checked the SMTP logs?

Actually, I don't think I understand well what you commented.
On the prompt windows, NSLookup could resolve address into IP.

I think I had better give more detail information.
Firewall is installed with NAT.
Server has inner IP setting and NAT translates between inner IP and pulbic IP.
Thanks a lot !

Do a NSLookup then type a question mark for help in selecting the type
of record.
