Some small updates from yesterday:
- added a graph for distinct hosts in greylist db
- to that end, now writing the two values I need from spamdb output to a temp file, so I don't have to run it twice
- changed colours for the graph lines (needs munin > 1.2.5 on the server)
- set lowest display value to 11 to better use space available for graphing (might need to be changed if trapped entries drop very low)
