Padding is invalid and cannot be removed.

Hi,

I'm regularly getting 2 errors on our site that we just installed on GoDaddy. Is anyone familiar with them and know a fix. They are happening all the time and filling up the log.

Thanks
Dawn

Not positive it's working, but we were getting the error so frequently that I think it is working. I used the information at this link to set a machineKey. It wasn't needed locally, but it is needed on GoDaddy.

I'm getting the same error on padding
Plus I get a mail error MailError
[The severity of the log entry.] Severity:   11
[The log entry message.] Message:   Error sending e-mail. Mailbox name not allowed. The server response was: sorry, your mail was administratively denied. (#5.7.1)

I got that error too. I ended up changing the code for btnContactUs_Click in Modules/ContactUs.ascx.cs to what is below. Not very clever, but it worked.

        protected void btnContactUs_Click(object sender, EventArgs e)
        {
            if (Page.IsValid)
            {
                try
                {
                    if (String.IsNullOrEmpty(txtEnquiry.Text))
                        return;
                    string email = txtEmail.Text.Trim();
                    string fullName = txtFullName.Text.Trim();
                    string subject = "Contact us form";
                    string body = txtEnquiry.Text.Trim();
                    //DH 11/2/2009
                    //Pre-Append "from" to body
                    string sFrom = "From: " + fullName + "(<a href=\"mailto:" + email + "\">" + email + "</a>)";
                    sFrom = HtmlHelper.FormatText(sFrom, false, false, true, false, false, false);
                    body = CommonHelper.FormatContactUsFormText(body);
                    body = sFrom + "<br /><br />" + body;
                    
                    //DH 11/2/2009
                    //Change from to equal to because from is not working on GoDaddy.
                    //(domain doesn't match URL)
                    //MailAddress from = new MailAddress(email, fullName);
                    //Replace from with to (both will be the same)
                    MailAddress from = new MailAddress(MessageManager.AdminEmailAddress, MessageManager.AdminEmailDisplayName);
                    MailAddress to = new MailAddress(MessageManager.AdminEmailAddress, MessageManager.AdminEmailDisplayName);
                    MessageManager.InsertQueuedEmail(5, from, to, string.Empty, string.Empty, subject, body, DateTime.Now, 0, null);

                    pnlResult.Visible = true;
                    pnlContactUs.Visible = false;
                }
                catch (Exception exc)
                {
                    LogManager.InsertLog(LogTypeEnum.MailError, string.Format("Error sending \"Contact us\" email."), exc);
                }
            }
        }
