Error in sending mail from server smtp?

Question

My mail sending code is as follows which has been hosted on the server:

try
    {
        MailMessage msgMail = new MailMessage();

        MailMessage myMessage = new MailMessage();
        myMessage.From = new MailAddress("*****");
        myMessage.To.Add(TextBox1.Text);
        myMessage.Subject = "Subject";
        myMessage.IsBodyHtml = true;

        myMessage.Body = "Message Body";


        SmtpClient mySmtpClient = new SmtpClient();
        System.Net.NetworkCredential myCredential = new System.Net.NetworkCredential("email", "password");
        mySmtpClient.Host = "****";  //Have specified the smtp host name
        mySmtpClient.UseDefaultCredentials = false;
        mySmtpClient.Credentials = myCredential;


        mySmtpClient.Send(myMessage);
        myMessage.Dispose();
    }
    catch (Exception ex)
    {
        Response.Write(ex.ToString());
    }

I keep on getting this error

System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: #5.1.0 Address rejected abc@yahoo.com at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at Mail.Button1_Click(Object sender, EventArgs e) in d:\hosting\9110120\html\FB\Mail.aspx.cs:line 37

I have tried everything.It keeps giving the same error

My site is hosted on Godaddy server

Is the address you are sending to a valid e-mail account? Some servers will reject mail immediately if the recipient is unknown. — Eric Petroelje, Mar 29 '12 at 17:16

Your code seems fine, apparently it could be that you need to configure it: http://support.godaddy.com/help/article/5444

When i am sending an email to myself on the server i receive it – vini Mar 29 '12 at 17:32
There maybe an issue with outgoing e-mails? If the e-mail works fine to yourself on the same server that would indicate your code is fine. – Darren Mar 29 '12 at 18:15

I had same problem , fixed it by a small change in the line below

System.Net.NetworkCredential myCredential = new System.Net.NetworkCredential("email", "password");

verify your credentials , that worked for me :) ..

It's failing because the email address doesn't exist. Just handle the exception and you should be all set.

How to check if an email address exists without sending an email?

The email i am actually specifying is correct this is just an example – vini Mar 29 '12 at 17:41
its an email address either gmail or yahoo and what do you mean inside a network? – vini Mar 29 '12 at 17:49
I think GoDaddy has a standard host for SMTP emails. What host are you using? And are you using the same credentials for logging into GoDaddy? – James Johnson Mar 29 '12 at 17:50
i have tried with both smtpout.secureserver.net and relay-hosting.secureserver.net ...... No i am not using the same credentials i have created an email address and password as was specified in Godaddy – vini Mar 29 '12 at 17:55
Try using the email address and password you use to login to Godaddy as the credentials. I had a similar issue before, and I think it had something to do with that. – James Johnson Mar 29 '12 at 18:06
I have solved my problem ! My stupid mistake thanks for helping ! – vini Mar 29 '12 at 18:24
