<pre>This part I do not agree with. Unless you think all RBL's contains more or less the same IP's, its pretty obvious that your protection improves with more RBL's.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Also unless you have resource contention in regards to multiple threads, the slowness RBL's introduce doesn't matter, and the system is just waiting for a response from the network, which almost doesn't consume any system resources.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Personally I have RBL's in both the MTA and in mailscanner. In the MTA I greylist based on a few very trustworthy RBL's and in mailscanner I score based on ohh I don't know 10-20 RBL's. It allows you to have a much more fine-tuned system instead of blocking based on a single RBL at the SMTP level.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>The advantage of having them in mailscanner is mainly that you can whitelist senders, the disadvantage is that senders aren't told that they are listed (but since all the RBL's I use are public db's used in thousands of systesm I trust somebody else will let them know soon enough :) )<o:p></o:p></pre>
