HELP! -
I have a C# .net application that sends email primarily and it is no longer working. Its very basic but its a down application at this point. I need some assistance in getting this up quickly:
//NEW SALES LEAD EMAIL
public bool SendNewSalesLeadEmail(SaveSalesLeadModel CR)
{
try
{
string smtpSetting = ConfigurationManager.AppSettings["smtpserver"];
SmtpClient smtpClient = new SmtpClient(smtpSetting, 587);
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
string _subj = "Customer Service Request Call-Confirmation";
string appName = ConfigurationManager.AppSettings["AppName"];
string MailSend = ConfigurationManager.AppSettings["MailSend"];
if (MailSend.ToUpper() == "ON")
{
string smtpemailFromName = ConfigurationManager.AppSettings["emailFromName"];
string smtpemailFromPwd = ConfigurationManager.AppSettings["emailFromPwd"];
string smtpemailAlias = ConfigurationManager.AppSettings["emailFromAlias"];
string smtpPort = ConfigurationManager.AppSettings["smtpPort"];
string currentEnv = ConfigurationManager.AppSettings["currentEnv"];
smtpClient.Credentials = new System.Net.NetworkCredential(smtpemailFromName, smtpemailFromPwd);
//smtpClient.UseDefaultCredentials = true; // uncomment if you don't want to use the network credentials
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
//Setting From , To and CC
mail.From = new MailAddress(smtpemailFromName, smtpemailAlias);
// mail.To.Add(new MailAddress("email address removed for privacy reasons", "Utz Customer Service Request-Admin"));
//mail.To.Add(new MailAddress("email address removed for privacy reasons", "Utz Customer Service Request-Admin"));
//PopulateSalesLeadRecipients(mail, CR, "1");
//mail.To.Add(new MailAddress(Sendto));
//mail.To.Add(HttpContext.Current.User.Identity.Name.ToString());
mail.Subject = "New Sales Lead";
