[Dovecot] dovecot sieve confusion

[Bazy]

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

?
