just a suggestion for improvement:
I think it would be helpful if the user had the option to get mail only when changes were detected.
Especially when running the scanner as a cron job, this would avoid "false alarms"
For the moment, that quick'n dirty hack in engines/finalization/email.php#53 works for me:
if( !($item->files_suspicious + $item->files_modified + $item->files_new) )
return true;
Best regards,
Jürgen.
