Over the past 7 days, I’ve received
506 511 (some came while writing this) pieces of spam. Of these, spamassassin correctly tagged about 450, a 90% hit rate, with no false-positives that I could see. Interestingly, mail.app’s internal junk-filtering rules gave me three false-positives. One of these was mailing-list mail with a spamassassin score of -9, two of them were paypal notices, one of which had a spamassassin score of -98! Interesting to note how disparate the two are.
