My post is based on installation problems with
amavisd-new and the message saying I didn't have one
as shown on original post error output. My googling
did tend to indicate that I need a different fqdn for
different program needs which blows my mind. I was
hoping the list new what I needed for local mail(root
mail and to install amavisd-new.

I'll review the above after this post.

Ok. But not:
192.168.1.64 ubuntu.gateway.2wire.net

OK. that means my question above is wrong.

I'll add that to /etc/host and see what happens.  And
yes, the move I read about fqdn the more confused I
get.  Thanks for trying; it's appreciated.
