Scott, I have been experimenting with some spam headers that our gateway
servers (Linux/Postfix/RAV AntiVirus) can add to potential spam messages.
One of the following four message headers can be added to a message based on
spam accuracy (or no header if the messages in not suspected of being spam):

X-RAV-Bulk: RAV AntiVirus classifies this e-mail as possible spam (accuracy
low)
X-RAV-Signature: FD532815A6484045B6E0C394EE0A9E8B

X-RAV-Bulk: RAV AntiVirus classifies this e-mail as spam (accuracy medium)
X-RAV-Signature: C07E06C3C9571C319503D70D526AE502

X-RAV-Bulk: RAV AntiVirus classifies this e-mail as spam (accuracy high)
X-RAV-Signature: 5F08B13CA5FD57F97700E6B5EC7ABDDE

X-RAV-Bulk: RAV AntiVirus classifies this e-mail as spam (accuracy very
high)
X-RAV-Signature: 0ED9D76FF782A37454E6F49CB13E25E5

I have the following entries in my filter file:

HEADERS 2 CONTAINS (accuracy low)
HEADERS 3 CONTAINS (accuracy medium)
HEADERS 4 CONTAINS (accuracy high)
HEADERS 5 CONTAINS (accuracy very high)

However, I have noticed that whenever these headers are added to an e-mail
message and tagged by the filter file, that none of the ip4r tests get run
on these messages--at least no ip4r tests get logged in the log file nor do
any show up in the headers.  All other tests get run (rhsbl, BADHEADERS,
BASE64,HELOBOGUS, HEUR7, IPNOTINMX, MAILFROM, PERCENT, REVDNS, ROUTING,
SPAMHEADERS), e.g.:

X-RAV-Bulk: RAV AntiVirus classifies this e-mail as spam (accuracy very

Service
X-Spam-Tests-Failed: NOPOSTMASTER, HELOBOGUS, IPNOTINMX, WORDFILTER,

X-Note: Total spam test weight: 36

I am trying to figure out what it is about these headers that would prevent
Declude from running the ip4r tests.  It does not appear that other entries
in the filter file prevent the ip4r tests from running.  I can send you
message samples and log files if you would like.

Thanks for looking into this.

Bill
