 if (error > 0) then
 begin
   logMsg('Service Error occured RqType:'+inttostr(integer(RqType))+' Error:'+vartostr(error));
   Exit;
 end;
 
 if RqType = smtpConnect then
 begin
   logMsg('Sending HELO');
   Smtp.Helo
 end
 else
 if RqType = smtpOpen then
 begin
   //open is easiest to use when you have the need for authentication
   logMsg('smtOpen, sending MailFrom');
   Smtp.MailFrom;
 end
 else
 if RqType = smtpHelo then
 begin
   logMsg('Sending from');
   Smtp.MailFrom;
 end

 if RqType = smtpMailFrom then
 begin
   logMsg('Sending to');
   Smtp.RcptTo;
 end
 else
 if RqType = smtpRcptTo then
 begin
   logMsg('Sending data');
   Smtp.Data;
 end
 else
 if RqType = smtpData then
 begin
   //here you need to generate the e-mail, and trigger more...
   if SendEmailQryEMAILID.AsString <>  then
   begin
     logMsg('Sending next email');
     generateSingleEmail; //a procedure i use to create my e-mail
     Smtp.MailFrom;
   end
   else
   begin
     logMsg('No more email to send, quitting.');
     Smtp.Quit
   end;
 end
