Delphi Indy

hi Experts

I am using Delphi2007 and Indy Direct 10.1.5 following code the Tech said no Authority required or TLS
       
          try
               try
                 idSMTP1.Connect;
                 idSMTP1.Send(IdMessage1);
               except on E:Exception do
                 Memo6.Lines.add('ERROR: ' + e.Classname + '  ' + E.Message);
               end;
               finally              
                 if idSMTP1.Connected then idSMTP1.Disconnect;
             end;

The Class name is EldSMTPReplyerror and the e.Message is Error

I want to create a log file using TidLogfile could you explain setting it up or why the eMessage doesn't give an error description or number

This program runs fine in other sites except for this one
