title: smtp web.config configuration and usage
body: <p>I have the following problem:</p>
  
  <p>Using asp.net C# and calling several places in code to send email to the user.</p>
  
  <p>However the from address in different sections of the code is different, and I have only one email address configured in web.config. This causes email sent from non-configured email addresses to go to users' junk box, how do I prevent this.</p>
  
  <p>I have the following in web.config. So if from any place in the code the from address i not hello123@site.com, it will go to users' junk box.</p>
  
  <pre><code>  &lt;smtp deliveryMethod="Network"&gt;
      &lt;network
        host="smtp.site.com"
        userName="hello123@site.com"
        password="mypassword"
      /&gt;
    &lt;/smtp&gt;
  </code></pre>
  
  <p>Here is c# code:</p>
  
  <pre><code>MailMessage message = new MailMessage();
  message.From = new MailAddress("forgotyourpassword@abc");
  message.To.Add(new MailAddress(this.txt_Email_Pass.Text));
  message.Subject = "Welcome to abc";    
  message.Body ="abc";
  SmtpClient client = new SmtpClient();
  client.Send(message);
  </code></pre>
