The instructions for the script say to use SPLITNCV_postfix instead of
NCV_postfix. The difference is that you would get one file called
postfix.rrd instead of 5 files called postfix,mails_active.rrd,
postfix,mails_bouncing.rrd, etc.

When not splitting, the text before the colon is used as the DS name, and
you have to keep that to under 19 (I think) chars, in which case
"mails_in_deferred_state" breeches that constraint, and so the RRD module
is probably rejecting all data.  When splitting, the text becomes part of
the filenames, and instead "lambda" is used as the DS name in each.
