[Dovecot] hide sieve folder from imap clients

Hello,

What is the best way to hide sieve folders from IMAP clients?

old config

mail_home = /var/vmail/%d/%n

plugin { sieve_dir = /var/vmail/%d/%n/.sieve/ sieve = /var/vmail/%d/%n/.dovecot.sieve }

new config (hide sieve folder)

mail_home = /var/vmail/%d/%n maildir_stat_dirs = yes

plugin { sieve_dir = /var/vmail/%d/%n/sieve/ sieve = /var/vmail/%d/%n/.dovecot.sieve }

Is there a better way without maildir_stat_dirs = yes ?
