Hello,

I have a simple Contact Us form module that sends an email that I am planning on implementing it on live, but i have been wondering what kind of security measures should I be paying attention to code wise or not.

                    mail.To = emailto.text;

                    mail.From = emailfrom.text;

                    mail.Subject = subject.text;

                    mail.Body = message.text;

                    mail.BodyFormat = System.Web.Mail.MailFormat.Html;

                    mail.BodyEncoding = Encoding.UTF8;

                    System.Web.Mail.SmtpMail.SmtpServer = "xxx.xxx.xxx.xxx";

                    System.Web.Mail.SmtpMail.Send(mail);

Note: Using dnn 7.2

Thanks,
