[Dovecot] lda_mailbox_autocreate and lda_mailbox_autosubscribe

Hello

I use real unix users on the mailhub and I would like to automate home directories creation for new users.

I found lda_mailbox_autocreate and lda_mailbox_autosubscribe statements in 15-lda.conf file ( dovecot 2.0.11 ) which seem to be the right things for me :-)

I use Postfix 2.8.1 with Dovecot LDA mailbox_command = /usr/local/libexec/dovecot/dovecot-lda

All Mailboxes are located in /user/$USER/mail/

Does those two statements means that if a home directory does not exists it will be created at the first login of the new user ?

I mean if new user "toto" has no homedir at all , dovecot will create /user/toto/mail at the very first successful connection ?

Thanks a lot
