There should be a postfix log giving more information.

Damn. Sorry, I didn't even notice that.  localhost should _never_ be 
anything but 127.0.0.1.  What happens when you ping localhost?  I'm thinking 
this is probably not a resolution issue, but that Postfix isn't actually 
listening on the localhost interface.  10.11.12.13 is probably your eth0 or 
wlan0 interface.  Which you probably don't want.

?  You mean like "nslookup localhost DNS-IP"?  I think that could only 
possibly tell you what the IP of "localhost" is on the DNS server (though, 
it should of course be 127.0.0.1).

That's the whole file?  It's a bit short for an ubuntu /etc/hosts.
