I've adjusted some of the MailScanner parameters to block GIF spam. Works ok (except for false positives on daily Dilberts), but a few appear to go through because SpamAssassin times out: SpamCheck: not spam, SpamAssassin (not cached, timed out). I've read (here) that it may have to do with Bayes database corruption. I would appreciate if someone would kindly point me in the right direction to solve this. Some more info: I have ConfigServer's (excellent) MailScanner package. There's a bunch of bayes_toks expire files in the /var/spool/mqueue/.spamassassin/ directory. I tried sa-learn --force-expire, didn't report any errors, but didn't get rid of the expire files.
