Sending Email Using C#

Question

Hi There
I'm trying to write a code that send email. Created a service, deployed in the server where i have configured the smtp settings.
When sending the email i'm getting the following error and also see the piece of code.
"The remote name could not be resolved. smtp.servername.edu.gov.za"

MailMessage mail = new MailMessage();

SmtpClient SmtpServer = new SmtpClient("smtp server");
mail.From =
new MailAddress("source");
mail.To.Add(
"destination");
mail.Subject =
"Testing";
mail.Body =
"Awe TestingL";
SmtpServer.Port = 25;

SmtpServer.EnableSsl =
true;

SmtpServer.Send(mail);
MessageBox.Show("mail Send");

May you please assist.

Thanks I think my smtp settings were not configured correctly. I'm finding difficult to do the smtp service testing

Could you please go little deeper into the exception details by checking the innerException messages by using following code . Try ' some code that is susceptible to throw exception. Catch ex As Exception Response.Write(ex.Message) While Not ex.InnerException Is Nothing Response.Write(ex.InnerException.Message) ex = ex.InnerException End While End Try It would be giving u the detail description of what might be the problem.Also check that there might be some problem in connecting to remote server as exception implies  WebException  the remote name could not be resolved . see this link. http://forums.asp.net/t/992641.aspx?WebException+the+remote+name+could+not+be+resolved or see this example ... using System; using System.Windows.Forms; using System.Net.Mail; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender EventArgs e) { try { MailMessage mail = new MailMessage(); SmtpClient SmtpServer = new SmtpClient(smtp.gmail.com); mail.From = new MailAddress(your_email_address@gmail.com); mail.To.Add(to_address); mail.Subject = Test Mail; mail.Body = This is for testing SMTP mail from GMAIL; SmtpServer.Port = 587; SmtpServer.Credentials = new System.Net.NetworkCredential(username password); SmtpServer.EnableSsl = true; SmtpServer.Send(mail); MessageBox.Show(mail Send); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } } }
