[Xymon] Setting up custom graph to monitor mail queue on postfix

[Ralph Mitchell]

I think your use of "lambda" in the DEF line may be wrong.  I think that
belongs to SPLIT_NCV, which is a different thing.

Take a look in data/rrd/servername for the postfix red files. You can dump
them out like this:

     rrdtool dump filename

The variable names will be in the header.
