smtp-vilter, spamassassin has error trying to read mail files
 

I recently set up smtp-vilter 1.1.4, SpamAssassin, and ClamAv 0.75 on Fedora Core 2, I am having problems with the three programs working together smtp-vilter seems to be working and I can send/receive mail, but spamd doesn't seem to be configured right or doesn't have the proper permissions. Here is a section of my mail log file with the errors (notice the lines from spamd, "Use of unitialized value"):

Could there be a problem with user or group permissions on any of the directories used by spamassassin? What user should spamassassin be running as, and what permissions are needed on the /tmp folder?

Thanks in advance for any help with this.
