Question

What am I doing wrong? Im trying to send a email using c# with GoDaddy webhost.

SmtpClient client = new SmtpClient("relay-hosting.secureserver.net", 465);
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("emailGODADDY", "password");

MailMessage message = new MailMessage("emailGODADDY", "otherEmail");
message.Subject = txtSubject.Text;
message.Body = txtContent.Value;

client.Send(message);

Answer 1

Each smtp server has own credentials which is not same with other.

According to microsoft client.UseDefaultCredentials should not be used
when possible.

You can try by omitting this line of code…..

client.UseDefaultCredentials = false;

If this will not work then try with

client.EnableSsl = false;

Because some server do not use secure connection.

You can check with this code also

client.DeliveryMethod = SmtpDeliveryMethod.Network;
