Writing a new DNSBL rule

[D . J .]

Hi all.  So I've got a DNSBL I want to use with SpamAssassin that wasn't included in the stock install.  My question (and there's an alarming lack of anything useful in this area... wiki anyone on the SA site?) is if my syntax and placement are correct for what I've done.  In my local.cf file, I've added the following lines:

(see the code at http://www.daringone.net/salines.txt - the list bounced this message for spam for some reason with the lines added)

It looks like all the other ones, but I'm not entirely sure what everything exactly does in the coding... so I took an educated guess.  Thanks for everyone's input.
