Password recovery with .NET using C#

I have this website with a login and a password recovery link. When I click the "forgot my password" link it takes me to a page which asks for username and security question answer. When I fill it out and hit submit. I am taken to a page that tells me the email was sent successfully but when I check my email, there is nothing there.
I'm hoping someone can tell me why I am not getting the password send to me. Here is my code.

<%@ Page Language="C#" MasterPageFile="~/BlogMasterPage.master" %>
<%@ Import Namespace="System.Net.Mail" %>
 
<script runat="server">
    protected void PasswordRecovery1_SendingMail(object sender, MailMessageEventArgs e)
    {
        MailMessage msg = new MailMessage();
        msg.From = new MailAddress("xxxxxxxxxx@gmail.com", "name");
        msg.To.Add(new MailAddress("xxxxxxxxx@hotmail.com", "name"));
        msg.Subject = "Test Mail";
        msg.Body = "It's another test, yet again!";
        msg.IsBodyHtml = false;
        msg.Priority = MailPriority.High;
 
        SmtpClient smtpClient = new SmtpClient();
        smtpClient.EnableSsl = true;
 
        smtpClient.Send(e.Message);
        e.Cancel = true;
    }      
 
</script>
 
<asp:Content ID="Content1" ContentPlaceHolderID="BlogMasterPage" runat="server">
    <br />
    <asp:PasswordRecovery ID="PasswordRecovery1" runat="server" OnSendingMail="PasswordRecovery1_SendingMail">
      <MailDefinition
         BodyFileName=""
         From="xxxxxxxxxxx@gmail.com"
         Subject="Password Recovery">
      </MailDefinition> 
 
     </asp:PasswordRecovery>
    <br />
</asp:Content>
 
 
<system.net>
    <mailSettings>
      <smtp from="xxxxxxxxxxxxx@gmail.com">
        <network host="smtp.gmail.com" password="xxxxxxx" userName="xxxxxxxxxxxxx@gmail.com" />
      </smtp>
    </mailSettings>
  </system.net>
