Ha! That’s nothing.
The first one I checked in my spambox scored 23.9 (composed in Netscape 4). And after checking a few more, I found a “refinance” spam that scored 42.1.

The folks who created SpamAssassin are having a “spam high score” contest - the person with the highest SA score wins 12 yummy cans of Spam. The last time I checked, the highest was 48 points.
(using TinyUrl because the URL from the SA news site is massive. Trust me, this is a legitimate link. Oh, the irony.)

Haven’t been having nearly as much fun with spam since I changed my email address. :-( I’m using popfile.
Ooooh, darn. My highest one so far *just* misses. My top 5 scores:
dougal:~/> grep SpamCheck: mail/spams | perl -e “while(<>){print m/score=([^,]+),/,qq(\n);}” | sort -n | tail -5
40.2
42.1
43.5
46.9
47.8
