[Mimedefang] Mail stats via rrdtool

[Fredrik Hansen]

I put this together via rrdtool, to get a quick&easy way to overview 
things:
http://pki.radioseven.se/status/graph.php?local_graph_id=57&rra_id=all

Its not as informative as graphdefang, I know - but on the other hand its 
easier to understand, and ill modify it when i find something more to 
graph.
(Avg size of mail, Avg CPU used/mail etc is things that can be useful,  maybe.)

Suggestions, improvements anyone?

Best Regards,
Fredrik Hansen
