Thanks. You need this option to run fetching emails manually for testing? The thing is that freescout:fetch-emails command is executed by cron at https://github.com/freescout-helpdesk/freescout/blob/master/app/Console/Kernel.php#L38

@freescout-helpdesk For testing yes, but mainly for initial import. The cron behaviour won't be affected as the default is still 3 days and the new option is optional.
