Sanesecurity not blocking messages

We have a properly functioning MailScanner server that I have recently
downloaded the sanesecurity definitions to. I am hoping that it will reject
the message the same way it does if there is a virus detection. I have
downloaded the update script and verified that the signature files are in
the same location as the main clamav databases. I assume it is ok to have
the following directory structure:
[root at mailscanner MailScanner]# ls -lah /usr/local/share/clamav/
total 4.4M
drwxrwxr-x 4 clamav clamav 1.0K Jul 31 08:30 ./
drwxr-xr-x 5 root root 1.0K Jul 3 17:09 ../
drwxr-xr-x 2 clamav clamav 1.0K Jul 31 06:05 daily.inc/
drwxr-xr-x 2 clamav clamav 1.0K Jul 20 13:07 main.inc/
-rw------- 1 clamav clamav 1.4K Jul 31 08:30 mirrors.dat
-rw-r--r-- 1 clamav clamav 514K Jul 31 07:50 MSRBL-Images.hdb

-rw-rw-r-- 1 clamav clamav 1.1M Jul 31 08:07 phish.ndb
-rw-rw-r-- 1 clamav clamav 182K Jul 31 03:19 phish.ndb.gz
-rw-rw-r-- 1 clamav clamav 1.1M Jul 31 08:07 phish.old

-rw-rw-r-- 1 clamav clamav 120K Jul 31 03:20 scam.ndb.gz
-rw-rw-r-- 1 clamav clamav 596K Jul 31 08:07 scam.old
This is what I am seeing in the log:

MailScanner dutifully sends the message on. It is flagged as a phishing
scam but no action is taken. Is there something I need to change in
MailScanner? It would appear that sanesecurity is doing its job but the
message still slips through. My apologies if this is not MailScanner
related. I searched google, the clamav site, the sansecurity site and the
MailScanner list archives extensively before writing. I appreciate any help
you could offer. Thank you.
