gethostbyname() cannot find host

[Phillip Deackes <gsmh@gmx.net>]

I keep getting emails in my inbox, (addressed to root but arriving in my
inbox because I have set this up in my aliases file) with the subject:

*** SECURITY information for scgf ***

The body of the message is:

scgf : Jan  6 21:46:15 : gsmh : gethostbyname() cannot find host scgf 

Irritating because I get a great many such messages (possibly coinciding
with when I use sudo?)

Any ideas would be very welcome!

Cheers.
