[SA-exim] greylisting under debain sarge

[gustav@xhostplus.at]

Hi,

I am using sa-exim-4.2-2 and would like use greylisting. Any time a mail 
arrives which has a score > SAtempreject spamd writes the following into 
the syslog file:

Reached greylisterror: creating 
/var/spool/sa-exim/tuplets/195/3/96/aon.912523521.ea at aon.at/erwin at nas.at 
/ Keine Berechtigung at 
/usr/share/perl5/Mail/SpamAssassin/Plugin/Greylisting.pm line 287.

Permissions of /var/spool/sa-exim/tuplets are temporarily set to 777.


Can one say me what this message means?
