How to configure SMTP to the remote computer?

vvsharma · Jun 5, 2007

Here are some sample codes for sending mail via your web application:

Asp.Net 2.0 (http://kb.discountasp.net/article.aspx?id=10443)
Asp.Net 1.1(http://kb.discountasp.net/article.aspx?id=10019)
Asp (http://kb.discountasp.net/article.aspx?id=10078)

In all the above,the smtp host should be set to 'localhost',while on DASP Servers

Hi there.
I've used Asp.Net 2.0 (http://kb.discountasp.net/article.aspx?id=10443) to send an email but all the time i get this message:

Any idea how to fix it?

Assuming the page is hosted on our server, this error usually means that you have not configured the SMTP server correctly. I recommend you double check your code to make sure it is set to localhost.

Your code looks ok to me, really not sure why you are getting the error message.
