Where Dovecot stores subscribtions for shared folder

Hi,

could please someone hint me, where Dovecot stores subscribtions for shared folder?

Our configuration:

namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared }

When I subscribe to 'user.test', I'll get ~Maildir/Shared/test/.INBOX/dovecot.index.pvt.log in it.

When I unsubscribe from 'user.test', file stays there and its hash is the same.

Kind regards, Milo
