 while (sr.Peek ()>0)
           {
               string str = sr.ReadLine();
               if(str.IndexOf ("Subjiect:")>=0)
               {
                   int start = str.IndexOf(":");
                   mail.Title = str.Substring(start+1).Trim();
               }
               else if (str.IndexOf("To") >= 0)
               {
                   int start = str.IndexOf(":");
                   mail.SendMail = str.Substring(start + 1).Trim();
               }
               else if (str.IndexOf("Cc") >= 0)
               {
                   int start = str.IndexOf(":");
                   mail.CC = str.Substring(start + 1).Trim();
               }
               else if (str.IndexOf("Date") >= 0)
               {
                   int start = str.IndexOf(":");
                   mail.DataTime = str.Substring(start + 1).Trim();
               }
               else if (str.IndexOf("From") >= 0)
               {
                   int start = str.IndexOf(":");
                   mail.ReceiveMail = str.Substring(start + 1).Trim();
               }
               else if (str.IndexOf("Message-Id:") >= 0)
               {
                   continue;
               }
               else
