ASP.Net MVC File Upload and Attach to Email - asp.net-mvc

Question

I'm developing an ASP.Net MVC 3 web application. One of my Razor Views allows a user to upload a file (selected from their computer) and then this is attached to an outgoing email.
Below is my code to date, but unfortunately it does not work. By this I mean the email (and of course the attachment) never gets sent. Although, when I step threw/ debug my code locally no errors occur, and none as well on the live server.
Does anyone see what I'm missing? Any advice would be greatly appreciated.
Thanks.
Controller
[HttpPost]
public ActionResult CvUpload(HttpPostedFileBase file)
{
//Get logged in user
User user = _accountService.GetUser(_formsAuthService.GetLoggedInUserID());
if (file != null && file.ContentLength > 0)
{
_emailService.SendUpload(user, file);
return RedirectToAction("CvUpload", new { feedBack = "Success" });
}
return RedirectToAction("CvUpload", new { feedBack = "Failed" });
}
Email Service
public void SendUpload(User user, HttpPostedFileBase file)
{
string messageBody = "";
string subject = "Upload";
string[] toAddress = new string[1];
string ToBCC = "";
if (isProduction.Equals("true"))
{
toAddress[0] = "myemail#test.com";
sendEmail(toAddress, ToBCC, adminFromEmail, adminFromEmail, subject, messageBody, true, emailServer, file);
}
else
{
// DO NOT SEND EMAIL
}
}
private bool sendEmail(string[] toAddresses, string ToBCC, string fromAddress, string replyto, string subject, string body, bool ishtml, string emailHost, HttpPostedFileBase file)
{
bool mailSent = false;
try
{
MailMessage mail = new MailMessage();
foreach (string addresss in toAddresses)
mail.To.Add(addresss);
mail.From = new MailAddress(fromAddress);
mail.ReplyToList.Add(replyto);
mail.Bcc.Add(ToBCC);
mail.Subject = subject;
mail.Body = body;
if(file != null && file.ContentLength > 0)
{
string fileName = Path.GetFileName(file.FileName);
mail.Attachments.Add(new Attachment(file.InputStream, fileName));
}
if (ishtml)
mail.IsBodyHtml = true;
else
mail.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = emailHost;
smtp.Send(mail);
mailSent = true;
}
catch (Exception)
{
mailSent = false;
}
return mailSent;
}

I have a similar service and this is what I have although the attachments are saved so they can be reused later.
var attachment = new Attachment(path);
ContentDisposition disposition = attachment.ContentDisposition;
disposition.CreationDate = File.GetCreationTime(path);
disposition.ModificationDate = File.GetLastWriteTime(path);
disposition.ReadDate = File.GetLastAccessTime(path);
disposition.FileName = attachmentName.Name;
disposition.Size = new FileInfo(path).Length;
disposition.DispositionType = DispositionTypeNames.Attachment;
mailMessage.Attachments.Add(attachment);
