Hi,
I've just read about bayesian analysis from
http://wiki.apache.org/james/Bayesian_Analysis. But I've lots of doubt.
First, I don't get what they mean with token frequencies or corpus.
Second, after understanding little bit about Bayesian from that sit, I tried
to in configure Bayesian analysis mailet, but it doesn't seem to work well.
Here's how I configured:
<!-- "not spam" bayesian analysis feeder. -->
<mailet match="recipientis=gr...@localhost"
class="BayesianAnalysisFeeder">
<repositoryPath> db://maildb </repositoryPath>
<feedType>ham</feedType>
<maxSize>200000</maxSize>
</mailet>
<!-- "spam" bayesian analysis feeder. -->
<mailet match="recipientis=...@localhost"
class="BayesianAnalysisFeeder">
<repositoryPath> db://maildb </repositoryPath>
<feedType>spam</feedType>
<maxSize>200000</maxSize>
</mailet>
<mailet match="All" class="BayesianAnalysis" onMailetException="ignore">
<repositoryPath>db://maildb</repositoryPath>
<maxSize>200000</maxSize>
<headerName>X-MessageIsSpamProbability</headerName>
<ignoreLocalSender>false</ignoreLocalSender>
</mailet>
<mailet match="CompareNumericHeaderValue=X-MessageIsSpamProbability
> 0.01" class="SetMailAttribute" onMatchException="noMatch">
<isSpam>true</isSpam>
</mailet>
<mailet match="CompareNumericHeaderValue=X-MessageIsSpamProbability
> 0.01" class="SetMimeHeader" onMatchException="noMatch">
<name>X-MessageIsSpam</name>
<value>true</value>
</mailet>
<mailet match="CompareNumericHeaderValue=X-MessageIsSpamProbability
> 0.01" class="ToProcessor" onMatchException="noMatch">
<processor> spam </processor>
<notice>Spam not accepted</notice>
</mailet>
<!-- Send remaining mails to the transport processor for either
local or remote delivery -->
<mailet match="All" class="ToProcessor">
<processor> transport </processor>
</mailet>
</processor>
I just passed on simple text message, to check whether it may go or not, but
unfortunately I can't see anything in spam folder in James. I passed
different messages to red and green. What's wrong I'm doing in above. Thanks
in advance.
