Scoring questions

[Computer Bob]

Greetings to all,

I have an issue with my setup somehow and it seems to be in amavis-new, 
most spam gets detected and delt with, some gets through and the scoring 
seems odd.
This one came in this morning and is typical of those that get through:

Return-Path: <rejuvalex at jodiariastrial.com> Subject: Regrow your Hair in 
3 Weeks.

X-Spam-Flag: NO X-Spam-Score: 1.995 X-Spam-Level: * X-Spam-Status: No, 
score=1.995 tagged_above=-9999 required=5 
tests=[HTML_FONT_LOW_CONTRAST=0.001, HTML_MESSAGE=0.001, 
PYZOR_CHECK=1.985, SPF_HELO_PASS=-0.001, SPF_PASS=-0.001, 
T_REMOTE_IMAGE=0.01] autolearn=no autolearn_force=no


If I run the email through on the command line with:
cat {mailfile} | spamassassin -D -t
The results are:
