the code is listed below:
<%@dotnet.itags.org. Page Language="VB" ClientTarget="downlevel" %>
<%@dotnet.itags.org. Import Namespace="System.Web.Mail" %>

If Page.IsValid() Then
strEmail = txtEmail.Text

myMessage.To = strEmail
myMessage.Subject = "E-mail Sample from ASP 101!"
myMessage.Body = "This message was sent from sample code by " & _
"http://www.asp101.com. It is used to show people how " & _
"to send e-mail from an ASP+ page. This mail was sent " & _
"from " & Request.ServerVariables("SERVER_NAME") & ". " & _
vbCrLf & vbCrLf & _
"This email was sent to " & strEmail & "."

' Doesn't have to be local... just enter your
' SMTP server's name or ip address!
myMail.SmtpServer = "localhost"
myMail.Send(myMessage)

frmEmail.Visible = False

<html>

Hello,

I'm beginner also, but what I would try is:

Change line:
myMessage.From = "webmaster@." & Request.ServerVariables("SERVER_NAME")

into:
myMessage.From = "your@.email.com"

and delete these lines:
' Doesn't have to be local... just enter your
' SMTP server's name or ip address!
myMail.SmtpServer = "localhost"

Rami,

it would also help if you would paste the exact error you are getting ... that will help in identifying your problem ...

cheers,

ok so the error is:

Server Error in '/ASP.NET/email' Application.

The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay for a@.a.com

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details:System.Runtime.InteropServices.COMException: The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay for a@.a.com
Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
  <%@. Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
   <system.web>
       <compilation debug="true"/>
   </system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

hmm, the error seems rather clear, what exactly did you do to solve it?
>The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay for a@.a.com
this means that the address you are sending to (a@.a.com) does not exist ...
to prevent this error to cause this page to display, you could add a Try ... Catch ... End Try statement around myMail.send(myMessage), like this:
Try
myMail.Send(myMessage)
Catch ex as Exception
End Try
Mind you, this only prevents the application to stop on the error, you should add code to handle the error properly
