The command is correct. You can get the same counters using `rspamc stat` command.
At minimum, 200 ham and 200 spam mails need to be learnt.

You can use both auto- and manual- at the same time. Autolearn is bad by itself as it cannot detect false positives. If you have decided to use autolearn for some reason (e.g. you want to use rejected mails to learn), set high thresholds like "autolearn = [-20, 20];" to minimize FP impact.
