[Dovecot] dovecot sieve confusion

Hi...

I use dovecot with postfix.

For dovecot's sieve plugin to work, do I need to put in my /etc/postfix/master.cf:

dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}

and

postconf -e virtual_transport=dovecot postconf -e dovecot_destination_recipient_limit=1

?
