///

public void SendMessage(string subject, string messageBody,string smsEmailAddress){MailMessage message = new MailMessage();SmtpClient client = new SmtpClient();//TODO: Add REGEX validation for email addressmessage.To.Add(smsEmailAddress);message.IsBodyHtml = false;// Set the subject and message body textmessage.Subject = subject;message.Body = messageBody;// Send the e-mail messageclient.Send(message);}}}This code connects to the SMTP server specified in configuration and sends a message.
