If you're using a hosting service, you will probably have to look up their documentation on the security/procedures they have for sending email. &nbsp;At any rate, below is a class I wrote to send email. &nbsp;Just plug in the IP address and port and other info that is unique to your web environment. 
 
Here is a email class that I wrote: 
&nbsp;
<pre><code class="code-10 nolinks" id="code-8224905">using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Mail;
using System.Web;

/// &lt;summary&gt;
/// Summary description for Email
/// &lt;/summary&gt;
public class Email
{
 public String From = &quot;noreply@your-domain.com&quot;;
 public String To = string.Empty;
 public String Subject = string.Empty;
 public String Message = string.Empty;

 public Email() { }

 public Email(string to, string subject, string message)
 {
 this.To = to;
 this.Subject = subject;
 this.Message = message;
 }

 public Email(string from, string to, string subject, string message)
 {
 this.From = from;
 this.To = to;
 this.Subject = subject;
 this.Message = message;
 }

 public Boolean Send()
 {
 SmtpClient smtp = new SmtpClient(&quot;mail.your-domain.com&quot;); //your smtp IP address here
 smtp.Port = 26;
 smtp.EnableSsl = false;
 smtp.Credentials = new NetworkCredential(this.From, &quot;your password&quot;);

 MailMessage mailmessage = mailmessage = new MailMessage();
 mailmessage.From = new MailAddress(From, &quot;From Title&quot;);
 mailmessage.To.Add(To);
 mailmessage.Subject = Subject;
 AlternateView html = AlternateView.CreateAlternateViewFromString(Message, null, &quot;text/html&quot;);
 mailmessage.AlternateViews.Add(html);

 try
 {
 smtp.Send(mailmessage);
 return true;
 }
 catch (Exception ex)
 {
 //TODO: possibly log error
 string error = ex.ToString();
 return false;
 }
 }
}
</code></pre>
 
 
Then to use it you would do something like shown below. &nbsp;Also, don't get too hung up on the activation key thing, I was just adding that in as a rough example of what I do when a users registers at one of my websites. 
&nbsp;
<pre><code class="code-10 nolinks" id="code-8224906">string email = &quot;username@email.com&quot;

/* some code to register (add to database) user */

string activationKey = MaybeGenerateAnActivationKey();

StringBuilder message = new StringBuilder();
message.Append(&quot;Somebody with this e-mail address registered a user account at www.your-domain.com.&quot;);
message.Append(&quot;&lt;br /&gt;&lt;br /&gt; To activate your registration, please visit the following page:&quot;);
message.Append(&quot;&lt;br /&gt; http://www.your-domain.com/Validate.aspx?key=&quot; + activationKey);
message.Append(&quot;&lt;br /&gt;&lt;br /&gt; Note that this page will expire in 24 hours, so act quickly.&quot;);
message.Append(&quot;&lt;br /&gt; If clicking the above link does not work, please copy and paste the link into your browser.&quot;);
message.Append(&quot;&lt;br /&gt;&lt;br /&gt; -------------------------------------------------------------------------------------&quot;);
message.Append(&quot;&lt;br /&gt; If you didn't request it, you may safely delete this message; we won't bug you again.&quot;);

Email mail = new Email(email, &quot;Your Domain Name: Activate Your New Account&quot;, message.ToString());
mail.Send();
</code></pre>
</div>

<div>
Ooops, just noticed a copy/paste flub-up. 
 
 
This: &nbsp; MailMessage mailmessage = mailmessage = new MailMessage(); 
 
 
Should be this: &nbsp; MailMessage mailmessage = new MailMessage();
</div>

<div>
Thanks for the code, but my project is in VB.NET, do you have VB.NET version. I don't understand why I need to enter the IP address and port information. I will deploy this product to a web server, do you mean I need the server's IP address and port information in order to use this feature?
</div>

<div>
Ok, so you need to know the IP address and port number that your mail server is using. &nbsp;Most hosting companies, such as GoDaddy, have several servers separated from their web servers, that do nothing but relay email. &nbsp;The hosting company will tell you the IP and Port needed to connect to these mail servers. &nbsp;At GoDaddy they are something like this: 
 
IP: yourdomain.secureserver.net 
Port: 25 
 
Also, almost all hosting companies have their mail servers setup to require a username and password when sending mail. The username is typically the email address, and the password is whatever password you used when setting up the email address. &nbsp;These are used to authenticate to the mail server so that only known email accounts can send email. 
 
Even if you are setting up your own web server in your house, the .Net Framework's email sending functionality requires the IP address and Port number, as they are needed for the system to know how to send the message over the network. 
 
Below is the above C# code converted to VB: 
&nbsp;
<pre><code class="code-10 nolinks" id="code-8224992">Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports System.Net
Imports System.Net.Mail
Imports System.Web

Public Class Email

 Public From As String = &quot;noreply@your-domain.com&quot;
 Public _To As String = String.Empty
 Public Subject As String = String.Empty
 Public Message As String = String.Empty

 Public Sub Email()

 End Sub

 Public Sub Email(ByVal _to As String, ByVal subject As String, ByVal message As String)

 Me._To = _to
 Me.Subject = subject
 Me.Message = message

 End Sub

 Public Sub Email(ByVal from As String, ByVal _to As String, ByVal subject As String, ByVal message As String)

 Me.From = from
 Me._To = _to
 Me.Subject = subject
 Me.Message = message

 End Sub

 Public Function Send() As Boolean

 Dim smtp As New SmtpClient(&quot;&quot;)
 smtp.Port = 26
 smtp.EnableSsl = False
 smtp.Credentials = New NetworkCredential(&quot;username&quot;, &quot;password&quot;)

 Dim html As AlternateView = AlternateView.CreateAlternateViewFromString(Me.Message, Nothing, &quot;text/html&quot;)

 Dim mailmessage As New MailMessage()
 mailmessage.From = New MailAddress(Me.From, &quot;Email Display Name&quot;)
 mailmessage.To.Add(Me._To)
 mailmessage.Subject = Me.Subject
 mailmessage.AlternateViews.Add(html)
 
 Try
 smtp.Send(mailmessage)
 Return True
 Catch ex As Exception
 Dim err As String = ex.ToString()
 Return False
 End Try

 End Function


End Class
</code></pre>
 
And to use it would be like this: 
&nbsp;
<pre><code class="code-1 nolinks" id="code-8224996">Dim email As String = &quot;user@email.com&quot;

Dim message As New StringBuilder()
message.Append(&quot;Some message text to send.&quot;)
message.Append(&quot;Some more stuff.&quot;)
message.Append(&quot;&lt;p&gt;Some embeded html in the email&lt;/p&gt;&quot;)

Dim mail As Email = New Email(email, &quot;Thanks for Registering&quot;, message.ToString())
mail.Send()
</code></pre>

Hi, 
 
Where in the form do I include the second part of your code? 
 
Thanks,

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
