For ASP.NET 2 you no longer using System.Web.Mail, but you will be using System.Net.Mail and the code to send email will be much simpler.
Below is the sample source code
1 MailMessage mail = new MailMessage();
2
3 //set the addresses
4 mail.From = new MailAddress("me@mycompany.com");
5 mail.To.Add("you@yourcompany.com");
6
7 //set the content
8 mail.Subject = "This is an email";
9 mail.Body = "this is the body content of the email.";
10
11 //send the message
12 SmtpClient smtp = new SmtpClient("mail.yourdomain.com");
13
14 //to authenticate we set the username and password properites on the SmtpClient
15 smtp.Credentials = new NetworkCredential("username@yourdomain.com", "secret");
16 smtp.Send(mail);
