Spamrats.com

[Michael Peddemors <mi...@linuxmagic.com>]

This may interest those playing with RBL checks in SA, we have released 
spamrats.com as a free RBL service now.

http://www.spamrats.com

RATS-NoPtr and RATS-Dyna will be the most useful, RATS-Spam is still in 
testing phase, so is not available yet.

This data is collected from ISP's all over north america, and is generated by 
the most virulant of RATS.  Normally in order to become listed, they will 
have triggered several checks, including rate limiters, and conform to 
signatures that indicate they are Bot or Trojan orientated.. rather than the 
more traditional use of Spam traps, so we do not expect false positives.

We actually recommend that RATS-NoPtr be used to block at the edge level, 
however you can use it as you see fit.

(Mail servers should have Reverse DNS right? And they sure should not be 
sending excessive amounts of email, to multiple ISP's)

RATS-Dyna might in theory get triggered by a mail server that uses 
Non-Conforming Best Practises for Reverse DNS, (but they also have to be 
sending abusive levels of email to get listed, and appear to be home PC style 
connections)

Have fun :)
