[Dovecot] lda protocol

Hello,

why the output of command "dovecot -n" doesn't show anything about protocol lda?

Bellow my lda configuration:

protocol lda { mail_plugins = sieve quota expire log_path = /var/log/dovecot-local-deliver.log mail_debug = yes postmaster_address = postmaster@domain.com hostname = mail01.domain.com mail_plugin_dir = /usr/lib/dovecot/modules/lda }

Thanks.
