I recently installed Amavis / SpamAssassin / ClamAV and was looking around for a good script to give me some statistics. The only script I found was

So from those terrible beginnings, I have pretty much rewritten the entire script. It works as advertised now. What I'm looking for is comments on what other things I can do to improve it.
