[exim] Problems using ClamAV

Hi,

I'm trying to integrate ClamAV with Exim.

I'm getting the following error for all mail deliveries:

2008-09-03 09:42:53 1Kan0v-0003eF-E8 malware acl condition: clamd: ClamAV returned /var/spool/exim/scan/1Kan0v-0003eF-E8: lstat() failed. ERROR


What did I miss?

Many thanks

Nico
