roundcube vacation module

[romantik]

Hi guys,

I have debian+ispCP1.0.0+postfix combo.

How can I configure vacation module for roundcube?

I'm enabled and configured this plugin, but I've got error message after committing vacation message:

Quote:CONFIGURATION ERROR

Vacation plugin: Cannot upload .vacation.msg. Check permissions and/or server configuration
Please read the INSTALL instructions!

config.ini

Code:

; Configuration file
;
;
; Syntax of this file is identical to php.ini where string values need to be quoted.
; See remarks there.
;
; To overrule the default settings, create a per-host key.
; See examples at the bottom of INSTALL.TXT
;

[default]
driver = "ftp"
subject = "Out of office"
body = "default.txt"


[dotforward]
binary = "/usr/bin/vacation"
flags = ""
message = ".vacation.msg"
database = ".vacation.db"
alias_identities = true
set_envelop_sender = false
always_keep_message = true

What am I doing wrong?
What drive should be adjusted and how?
