[mrtg] mrtg is spamming me

First, I am totally new with mrtg. I've read the config
reference manual, the faq, and other stuff but I may have
missed something.

I installed mrtg-2.17.0 packaged for Fedora-15. I used
cfgmaker to generate a working config file for one server
and one client (a laptop) machine. Things seemed to be
working correctly until I shutdown the laptop.

Now, every 5 minutes, I get an email:

2011-11-21 17:30:01: WARNING: Could not match host:'public at haru:::::2' ref:'Ip' key:''

Here is the config file (I deleted the server section since
it's not relevant I think.)

How do I tell mrtg to ignore a machine that is
