OK, I took a look at it.

It seems to be just another digest system, although I don't understand 
what it uses to generate the hash.  But, once you have a hash, I can't 
see how that would magically detect spam.

Now, it does appear that it might be able to recognize it as similar to 
spam you have already received, but there is zero documentation on how 
to do that.  And, it would mostly be useful as a distributed database, 
but there doesn't appear to be anything like that available, either.

So, how does one use this in the real world?

BTW, only 25% of connections to my mail servers result in SA running, 
so I don't think it will help me much, but it's probably worth some 
time to look at.
