I like Razor, it catches stuff that nothing else does, and volume is inherent to spam.
BUT its precision is shot lately.
AND because it never sees content, it can't adjudicate disputes over spamminess in
order to award trust to the folks who are really right.

Here's my score for Bruce's newletter from SpamAssassin 2.50-cvs
(1.168-2003-02-09-exp):
Content analysis details: (1.70 points, 6.2 required)
DOMAIN_BODY (0.0 points) BODY: Domain registration spam body
OPT_IN_CAPS (0.4 points) BODY: Talks about opting in (capitalized version)
BAYES_20 (-0.1 points) BODY: Bayesian classifier says spam probability
is 20 to 30%
[score: 0.2634]
RAZOR2_CF_RANGE_01_10 (0.0 points) BODY: Razor2 gives a spam confidence level
between 1 and 10
[cf: 4]
MIME_LONG_LINE_QP (0.5 points) RAW: Quoted-printable line longer than 76
characters
NORMAL_HTTP_TO_IP (0.9 points) URI: Uses a dotted-decimal IP address in URL
RAZOR2_CHECK (0.0 points) Listed in Razor2, see http://razor.sf.net/
Note:
This is after I did a razor-revoke. RAZOR2_CF before my revoke was 16.
I guess that reveals my trust level in Razor2.
Note:
Earlier versions that gave RAZOR2_CHECK a weight of 3.9 would have put
me over the default 5.0 threshold.
