I just discovered that my spam filters are not being properly executed in CentOS 5.3 because when procmail attempts to invoke spamc. I have spamd running properly, and can invoke spamassassin and spamc from the bash prompt manually without any issues, however procmail fails with "permission denied" then bails. Watching the procmail.log I get the following:
