This ended up causing some major changes to the way Hobbit handles RRD
files, but I think it has improved.

Hobbit will now auto-detect what datasets are in an existing RRD file,
and use this to select what data to update the RRD-file with. So if you 
have an existing RRD file without the new field,  it will continue to
use that format (and you dont get the new field data tracked). If Hobbit
creates a new RRD file it will include the new field, and track data 
for it.

So it should work for all Sendmail versions, and remain compatible with
the existing RRD's.
