                            FileNm = System.IO.Path.GetFileName(postfiles.FileName.ToString());

                            //Save the File to the Directory (Folder).

                            FUAttchmnts.SaveAs(folderPath + Path.GetFileName(FileNm));

                            Msg.Attachments.Add(new Attachment(folderPath + Path.GetFileName(FileNm)));

See small change in my code. I am now saving files in Uploads folder and it works fine.

if (fuAttachment.HasFile)
{
    foreach (HttpPostedFile file in fuAttachment.PostedFiles)
    {
        string fileName = Path.GetFileName(file.FileName);
        file.SaveAs(Server.MapPath("~/Uploads/") + fileName);
        mm.Attachments.Add(new Attachment(file.InputStream, fileName));
    }
}
