[exim] problem with .forward

Hello exim folks.
i have problem with executing .forward files.
my userforward and localuser parts :
-----------------------
userforward:
driver = redirect
allow_filter
check_ancestor
check_local_user
no_expn
file = $home/.forward
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply
no_verify

localuser:
driver = accept
check_local_user
transport = local_delivery

local_delivery:
driver = appendfile
delivery_date_add
envelope_to_add
file = /var/mail/$local_part
group = mail
mode = 0660
return_path_add
user = ${local_part}
-------------------------
and when i will create a .forward file in some home directory
[root@server test2]# cat .forward
"|/bin/touch lll"
while sending mail it is executed(file created) , but mail isnt
delivered. logs shows me that mail has been delivered by "completed"
command.
I dont know where to look for errors. please send any suggestions.
