    // If your IMAP4 server requires SSL connection
    // Please add the following codes
    // oServer.SSLConnection := true;
    // oServer.Port := 993;

    oClient := TMailClient.Create(Application); 
    oClient.LicenseCode := 'TryIt'; 

    oClient.Connect1(oServer.DefaultInterface); 
    ShowMessage( 'Connected!' ); 

    infos := oClient.GetMailInfos(); 
    UBound := VarArrayHighBound( infos, 1 ); 
    Count := UBound+1; 
    ShowMessage(Format('Total %d email(s)', [Count])); 

    For i := 0 To UBound Do 
    Begin 
      oInfo := IDispatch(VarArrayGet(infos, i)) As IMailInfo ; 
      ShowMessage(Format('Index: %d; Size: %d; UIDL: ' + oInfo.UIDL, 
      [oInfo.Index, oInfo.Size])); 

      // Generate a random file name by current local datetime,
      // You can use your method to generate the filename if you do not like it
      fileName := mailFolder + '\' + oTools.GenFileName(i) + '.eml; 

      // Receive email from IMAP4 server
      oMail := oClient.GetMail( oInfo ); 

      ShowMessage( 'From: ' + oMail.From.Address + #13#10 + 
        'Subject: ' + oMail.Subject ); 

      // Save email to local disk
      oMail.SaveAs( fileName, true );
