Symantec bought [Turntide]. If I'm not mistaken, they quietly killed
it off a while back.
As far as I know, they made it really expensive. It isn't dead.
It's odd that they'd make it more expensive -- when I'd proposed it on
FoRK (2001?) I'd imagined it'd be the sort of thing that people would do,
not the sort of thing that they'd buy.
So my initial reaction was to guess that Symantec killed it off because
anyone large enough to drop 20k USD on an anti-spam box was also large
enough to spend a couple of days writing one in-house.
(In any case, I am glad to see that it's at least been tried)
