I've been there for two or three years (on the razor list). But the issue of effectiveness is largely ignored.
Regardless of how it is trained, Razor's basic design allows it only to catch allready known spam, whereas other filters can set the spami-ness of never before seen spam with suprizing effectiveness.
That posses a question. I'm getting a kind of spam (it started a few months ago) that is hard to catch by spamassassin: a link to an image (which I assume is the "message") and a more or less long paragraph full of random text, aimed at rendering bayessian filters useless.
How can we best filter out those? I suppose something like "razor" should work, at least for those that do not get them first.
But I have never tried razor.
bogofilter may be an option for you. One of the features that bogofilter has an advantage is that it will decode mime encoded email messages. I don't believe that spamassassin will do this. It also uses the links in html tags as tokens for determining spam. I've played with it for a few days and it seems excellent, but I think I hosed things up a bit this morning with a new install. My word database might not be valid anymore.
