SmtpServer error

Hi all
I can't seem to trace what is causing the SmtpServer to respond : " Mailbox unavailable. The server response was: sorry, no mailbox here by that name (#5.1.1) "

Stack Trace:

[SmtpFailedRecipientException: Mailbox unavailable. The server response was: sorry, no mailbox here by that name (#5.1.1)]

MailDefinition md = new MailDefinition();

            md.IsBodyHtml = true;
            md.Subject = "Report Repairs from " + your_name.Text;

            //Get Managers email
            ReceipientAdddresss = prsnj.bll.portfolio.GetManagersEmail(Convert.ToInt16(properties.SelectedItem.Value));

                ListDictionary replacements = new ListDictionary();
            replacements.Add("<%date%>", ReportDate.Text);
            replacements.Add("<%tenant_name%>", tenant_name.Text);
            replacements.Add("<%your_name%>", your_name.Text);
            replacements.Add("<%property%>", properties.SelectedItem.Text);

            if (SubDivision.Items.Count != 0)
                replacements.Add("<%SubDivision%>", SubDivision.SelectedItem.Text);
            else
                replacements.Add("<%SubDivision%>", "None");

            replacements.Add("<%email%>", email.Text);
            replacements.Add("<%phone%>", phone.Text);
            replacements.Add("<%repair_type%>", repair_type.SelectedItem.Value.ToString());

            MailMessage msg = md.CreateMailMessage(ReceipientAdddresss, replacements,
                body, new System.Web.UI.Control()); 

            
           

            msg.Priority = MailPriority.Normal;

            SmtpClient mSmtpClient = new SmtpClient(ConfigurationManager.AppSettings["SmtpServer"]); //Set smtp in web.config file

  
            
            mSmtpClient.Send(msg);

            Status.Text = SuccessMsg;

Your smtp server might require authentication and It does not seem you have set the credentials using  Credentials property. Set the valid credentials and try.

What value do you get for ReceipientAdddresss =>
MailMessage msg = md.CreateMailMessage(ReceipientAdddresss, replacements,  
                body, new System.Web.UI.Control());  
 
Here is the description of your error:

SMTP Error 511 : Bad email address. This error is
similar to error 510 and as with error 510, this status code
is generated by the sender’s local mail server.
If the email was addressed internally, then it means that
the addressee, as written in the email’s TO, CC, or BCC
fields, does not exist in your organization’s email system.
