imap_hibernate_timeout = 5 secs

service imap-hibernate {
   extra_groups = $default_internal_group
   unix_listener imap-hibernate {
     group = dovecot
   }
   user = vmail
}

service imap {
   extra_groups = $default_internal_group
   unix_listener imap-master {
     group = $default_internal_group
   }
}

I tried to set user/group vmail, set mode = 0666, but the same errors.


Can you help me with hibernate confiration ?



Best regards,
