You tried to use clasic asp code in ASP.NET page and that's why it's not working. You should try with this:

System.Net.Mail.SmtpClient email = new System.Net.Mail.SmtpClient();
        System.Net.NetworkCredential credential = new System.Net.NetworkCredential(System.Configuration.ConfigurationSettings.AppSettings.Get("sendusername").ToString(), System.Configuration.ConfigurationSettings.AppSettings.Get("sendpassword").ToString());
        email.Host = System.Configuration.ConfigurationSettings.AppSettings.Get("smtpserver").ToString();
        email.Credentials = credential;
        System.Net.Mail.MailMessage mailMsg = new System.Net.Mail.MailMessage();
        mailMsg.From = new System.Net.Mail.MailAddress(System.Configuration.ConfigurationSettings.AppSettings.Get("sendusername").ToString());
        mailMsg.To.Add(new System.Net.Mail.MailAddress(System.Configuration.ConfigurationSettings.AppSettings.Get("emailto").ToString()));
        mailMsg.Subject = "Enquiry Email from Web Visitor";
        mailMsg.Body = strEmailText;
        mailMsg.IsBodyHtml = true;
        email.Send(mailMsg);

That's why the code isn't working - it's for .NET 2.0 and above. To solve your problem, take a look at this article: http://uxuf.blogspot.com/2006/08/sending-mail-with-systemwebmail-net-11.html
