testing spam gives warn config error

[Kate Kleinschafer]

Hi all,

I have a new install of MailScanner / Postfix / Spamassassin
when I run sudo -u postfix spamassassin -p 
/etc/MailScanner/spam.assassin.prefs.conf -t < message.MAI
I get the following error:
warn config path /root/ .spamassassin is inaccessible permission denied
How can I resolve this error?

Thanks
Kate
