I'm looking for a package to report on spam stats. In particular I'd like to know which spamassassin categories have had most hits. I know of Vispan (http://www.while.org.uk/mailstats/), MailWatch (http://mailwatch.sourceforge.net/doku.php) and mailscanner-mrtg (http://sourceforge.net/projects/mailscannermrtg). Any others? Recommendations?
