That is not a valid address. When you use IP instead of hostname (or want
to ignore MX) it has to be in brackets: root@[]

It might be easier if you set up dynamic DNS. I use for my
dynamic adsl (pppoe) and run its update client from /etc/ppp/ip-up (which
runs whenever ppp gets an IP). Then set that name as your hostname and
assign it to a static IP in /etc/hosts so your box can find itself. If
you have no static interface, use an extra loopback IP like

You can find other dynamic DNS services by google searching for 'dns
