Can't send mail in ASP.NET?

Question

Guys I am trying to send an email using the code below in ASP.net but it is not working. However, the same code works for win forms. I am using c#. What seems to be the problem?

    try
    {
        using (System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage())
        {
            message.To.Add("//some id");
            message.Subject = "New Ticket Generated";
            message.From = new System.Net.Mail.MailAddress("//id");
            message.IsBodyHtml = true;
            message.Body = "This is message body";

            using (System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient())
            {
                smtp.Host = "// smtp host";
                smtp.Credentials = new System.Net.NetworkCredential("// username", "// pass");
                smtp.Send(message);
            }
         }
    }
    catch { }

i think you have missed some codes to write to work it in asp.net

codes are
smtp.Port = "port number";
smtp.EnableSsl = true;
smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = false;

follow these are some codes which may help you

try
    {
        using (System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage())
        {
            message.To.Add("to emailadress");
            message.Subject = "New Ticket Generated";
            message.From = new System.Net.Mail.MailAddress("from emailaddress");
            message.IsBodyHtml = true;
            message.Body = "This is message body";
            System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
            smtp.Host = "smtp.gmail.com";
            smtp.Port = 25;
            smtp.EnableSsl = true;
            smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            smtp.UseDefaultCredentials = false;
            smtp.Credentials = new System.Net.NetworkCredential("yourEmailid", "yourpassword");
            smtp.Send(message);

        }
    }
    catch(Exception)
    {
        throw;
    }

N.B- here i am using gmail smtp server and port, for that you must use an gmail Email address in "from emailaddress" and in smtp.Credentials = new System.Net.NetworkCredential("the same email-id from emailaddress", "the password of the from emailaddress ");

for example

message.From = new System.Net.Mail.MailAddress("rahul@gmail.com");
smtp.Credentials = new System.Net.NetworkCredential("rahul@gmail.com", "myp@ssword");

follow this link to get reference of all smtp server details http://www.arclab.com/en/amlc/list-of-smtp-and-pop3-servers-mailserver-list.html

try it and goodluck

Check the following:

• Check the line in your code message.To.Add("//some id"); and make sure it's something like mail.To.Add(new MailAddress("someone@company.com")); //Make sure correct email address
• Catch and handle (i.e. log, display exception message). If you don't catch here and let the exception propagate up to the caller, the caller needs to catch and handle.

• Refer to the documentation

  http://msdn.microsoft.com/en-us/library/swas0fwc%28v=vs.110%29.aspx

and look at all possible exceptions that SmtpClient.Send() method can throw. More than likely, I think it's SmtpException that gets thrown or a little less likely SmtpFailedRecipientsException.

• Without knowing your environment, I'm guessing you are trying to run this program from your desktop. Check with your system admin that no virus program such Symantec Endpoint Protection or something like that blocks the smtp port. If you indeed run from the server, check anyway that the port is not blocked and/or the smtp server dns name is correct (try IP address instead).
