Error during send of Email

[jstansell]

I was wondering if anyone else has seen this error when sending an email in VB.Net using the SMTP service. I have verified that the to and from email address are correct. What else could be causing this.

It looks like you are getting a "Relaying Denied" error.
Here is what MSDN says about the error when trying to send mail through VB.NET and getting this error

This is due to your SMTP server configuration. Your server is probably locked down in some way to prevent spammers from abusing your mail server. To find out how to better use your server, please contact your mail server administrator.

Thanks, but I already had configured the Relay info as needed. Acutally, we found that it was Norton Anti Virus causing the problem. Once we turned off the email scan, it worked fine. Thanks anyway!
