Is it just me that gets loads of files bayes_toks.expire* filling up /var/spool/spamassassin/nobody ?
I seem to get a 10MB file of this form in there for every single email - for every user - SA handles :(
I didn't get any replies, but for the archives: I fixed this by removing the sticky bit (mode 01000) from the /var/spool/spamassassin/nobody directory.
cheers, c.
