Please format correctly. What is the exception you are getting? Note: if you copied and pasted the code above from your class there is a missing quote mark at: new NetworkCredential("", "PWD",";

I want a exact error code - to put it in your words. How can we help you if you don't give any details as to what the error actually is!? "Timeout or failure" covers just about every error possible!

/???i dont know where is error in my code
Ed Nutting 8-Mar-12 16:32pm
apparently... look the code must be either throwing an exception - in which case you need to put a try/catch block round it and gives us the specific error message - or the web server is returning an error code/message so you need to tell use what that is.

Change your port number to 587 and try once.

Refer this code

public int SendUserMail(string fromad, string toad, string body, string header, string subjectcontent)
        int result = 0;
        MailMessage usermail = Mailbodplain(fromad, toad, body, header, subjectcontent);
        SmtpClient client = new SmtpClient();
        //Add the Creddentials- use your own email id and password
        client.Credentials = new System.Net.NetworkCredential("your user id ", "pwd"); ;
        client.Host = "";
        client.Port = 587;
        client.EnableSsl = true; 
            result = 1;
        catch (Exception ex)
            result = 0;
        } // end try 

        return result;
    public MailMessage Mailbodplain(string fromad, string toad, string body, string header, string subjectcontent)
        System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
            string from = fromad; 
            string to = toad; 
            mail.From = new MailAddress(from, header, System.Text.Encoding.UTF8);
            mail.Subject = subjectcontent;
            mail.SubjectEncoding = System.Text.Encoding.UTF8;
            mail.Body = body;
            mail.BodyEncoding = System.Text.Encoding.UTF8;
            mail.IsBodyHtml = true;
            mail.Priority = MailPriority.High;
        catch (Exception ex)
        return mail;
