I have little to no experience with sending emails in C#, so any help here would be appreciated. All I know is that you have to use the System.Net.Mail namespace. I tried this code but it gave an "Failure sending Mail" exception.

        new SmtpClient("smtp.server.com", 25).Send("test@hotmail.com",
                                       "test@gmail.com",
