[sentinix-list] Sentinix Mail Reporting

What is the best way to monitor/report on the postfix/MailScanner?  I am
currently using the sentinix box to act as a spam firewall for my
exchange server, but I would like to be able to graph the number of
messages accepted/rejected/spam score, etc.  Has anyone set this up
using the included Cactus/RRDTool package?  
 
I did come across a package called mailgraph
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool which is supposed to
be a work with RRDTool, but I have no clue if this will work with the
sentinix configuration.
 
Thanks in advance
