OK, I'm sure this is the problem.

oops.  Sorry, I meant to write /etc/hostname.  Nevermind, though, you've got
that part working.

Ohhh...  I don't think you can do that.  Is "ubuntu" supposed to map to or

But gateway.2wire.net doesn't seem to resolve, either, which is why NoOp is
suggesting setting up a DDNS account.

Since it's only amavis that seems to be complaining, there's almost
certainly somewhere in the amavis config where you can specify an FQDN, but
I've never used it.

Personally, I think you're trying to do too much.  Why don't you uninstall
amavis, and get your mail working _first_.
