Q. How to send e-mail from an ASP.NET application?

Answer: # 1 MailMessage message = new MailMessage ();
                 message.From = <email>;
                 message.To = <email>;
                 message.Subject = "Scheduled Power Outage";
                 message.Body = "Our servers will be down tonight.";
                 SmtpMail.SmtpServer = "localhost";
                 SmtpMail.Send (message);

MailMessage and SmtpMail are classes defined in the .NET Framework Class Library's  System.Web.Mail namespace.Due to a security change made to ASP.NET just before it shipped,  you need to set SmtpMail's SmtpServer property to "localhost" even though "localhost" is  the default.In addition, you must use the IIS configuration applet to enable localhost  (127.0.0.1) to relay messages through the local SMTP service.
