Hi Buddies,

  FROM mailbox WHERE username = '%u' AND active = 1
user_query = SELECT concat("/var/vmail/", maildir) as home, 125 as uid, 125
as gid FROM mailbox WHERE username = '%u'

I use mailbox in nfs share.
When i set the option "mail_nfs_index = yes" the dovecot fails to start.

Looking at logs, only prompted this:

"Feb  6 11:07:25 picapau kernel: [ 1436.376023] init: dovecot main process
(4177) terminated with status 89" without more info.
