[exim] exim/spamd problem

I keep getting the following in my exim_paniclog :
2007-02-08 13:16:16 1HF7BY-00067v-Jc spam acl condition: all spamd
servers failed
2007-02-08 13:16:17 1HF7G5-0006Wl-Sw spam acl condition: warning - spamd

I can telnet to 127.0.0.1:783, that seems to be working. Spamd is also
working.
Running exim 4.50

Anyone know what I should be looking for?

Thanks
Paulo
