           string subject = Txtsubject.Text;
           string mailbody = txtname.Text+"\n"+Txtemail.Text+"\n"+Txtbody.Text;

           var client = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587)
           {
               Credentials = new System.Net.NetworkCredential(myEmailAddress, mypwd),
               EnableSsl = true
           };
           client.Send(myEmailAddress, toEmailAddress, subject, mailbody);

Godaddy doesn't work well with gmail and others. Use the Godaddy server where you have a mail account. You don't need to supply the server name or port, just your credentials. You probably won't find this mentioned on the godaddy forums or help.

Why don't you look around at godaddy forum[^]? There you have your answer multiple times:

Quote:
When you’re sending mail through your hosting account, be sure you’re using this as your SMTP server: relay-hosting.secureserver.net

As I see you can't use google mail server there....

Man! What about a minute of digging on your provider's support pages? Should I do it for you? Why?
Well, I have found the answer. You could have found it too.
