Sometimes, even if you've changed the host name via raspi-config, the settings don't stick. To make it permanent:

sudo nano /etc/hosts

and change the line that says

127.0.1.1       raspberrypi

to

127.0.1.1       myhostname

assuming that myhostname is the name you want to use. Save, exit and reboot, and the message will go away.
