[Dovecot] Autosubscribe new folders

Hi,

I have a sieve filter:

require ["fileinto","reject","body"];

if header :contains "subject" "NOTE" { if body :content "application/pdf" :contains "" { redirect "notes@domena.com"; } else { reject text: Lack attachment PDF! . ; stop; } }

When I get a new message, in user folder is automaticly created folder like subject but is not subscribed. What I must settings in dovecot to automaticly subscribe folders to subscriptions files.?
