[Exim] root's .procmailrc

I need to get Exim to be able to read root's .procmailrc file
I have this director/transport and it works for all other users:

*Transport*
procmail_pipe:
driver = pipe
command = /usr/bin/procmail -d $local_part
return_path_add
delivery_date_add
envelope_to_add
check_string = "From "
escape_string = ">From "
user = $local_part
group = mail

*Director*
procmail:
driver = localuser
transport = procmail_pipe
require_files = $local_part:$home/.procmailrc

And I get this error(only when sending to root@???)
15s61F-00044r-00 == root@??? T=procmail_pipe defer
(13): Permission denied: failed to chdir to /root
How can I tell Exim to pull down its security blanked and allow this?

Thanks,
