Alex,

So yes - this one *is* the official/defacto version for SpamAssassin. 
This one was developed in coordination with the Apache Foundation and 
its development was partially funded by invaluement. The problem here is 
that the main developer (to his credit - this is a GOOD problem!) got 
ahead of us with the implementations. But we're in the process of 
catching up on the data-generation side, and hope to have those new 
types of data released in the next few weeks (for those ones mentioned 
in those rules, and for other ESPs that will get into those rules 
eventually).

The entire process of developing the engine that produces that SendGrid 
data - was the equivalent of our entire invaluement staff taking at 
least a full month of paid leave away from our regular duties. So that 
got us horribly behind on other things - including getting this data 
into our regular paid datafeeds with instructions sent to our customers 
for that - so we're still catching up on all of that - but we hope to 
get past that soon and to also have those /*other*/ related datafeeds 
for our "service provider DNSBL" released soon. (it won't be as much 
work for the other ones, now that the sendgrid anti-spam data engine is 
already completed - it "blazed the trail") So that explains why a few 
months have passed since the sendgrid data was released without any 
additional data being released yet, and how/why the developer of the 
rules was able to get ahead of us. (again, to his credit!)

Thanks for your patience and understanding.
