Reporting tools roundup

[Phil Iovino]

I'm looking for input on any/all of the following reporting tools -

mrtg-mailstats -
http://www.earlham.edu/~littejo/software/mrtg-mailstats.html

spamstats.pl - http://www.gryzor.com/tools

mailscanner-mrtg - http://mailscannermrtg.sourceforge.net

mailwatch - http://sourceforge.net/projects/mailwatch

mailstats - http://www.while.homeunix.net/mailstats

If I'm missing any please let me know. I'm planning on making a reviews
page on reporting tools for MailScanner/SpamAssassin. Thanks!
