milter-link works on content, not the connection nor envelope. In the 
month or so I've been using it prior to its release, I've not had one 
false-positive and I tested it with the aid of someone's spam trap so it 
was stressed tested and checked against a wide variety of input (the 
only false-positives during initial development were do to coding 
errors), but essentially the three URI BLs consulted have never caused 
me any grief.

The attached graph shows the spam trap activity in the last 24 hours. It 
compares DNSBL and URI BL. rejections.

True. But milter-link doesn't do anything really fancy yet. Version 0.2 
that I'm working on now identifies a certain class of spam (pump & dump 
stock spam appearing as a .gif) through its MIME structure.
