This is a pretty good sign of a forgery, or at least a potential
forgery. If the "Received: from X" is ridiculously different from
what's in the parentheses after it, it's suspect (but this, too, is
merely a good guess). 

Not really.  :)  Depending on how one sets up their home machine, this is
quite possible.  Note that when I bother to connect via PPP (or Slirp) my
email headers do look like this.  Becuase that X is Vallhalla or Asgard or
Doghouse depending on the PC I connected with.

The Message-Id doesn't contain a valid host name. Legitimate software
does this, too, but it's another thing to look out for. 

I use heavy scoring against any message where the message-id does not end
in a legit domain.
