Real headers, domains changed to protect the innocent:

Return-Path: <a.user@xxxxxxxx>
Received: from xxxx.xxxx.net (xxxx.net [aaa.bbb.ccc.ddd])
        by my.domain.com (8.8.8/8.8.8) with ESMTP id HAA18887;
        Sat, 30 Sep 2000 07:14:45 +0100
Received: from laptop.xxxx.net (userbl35.uk.uudial.com [62.188.144.142])
        by xxxx.xxxx.net (8.9.2/8.9.2) with ESMTP id GAA22375;
        Sat, 30 Sep 2000 06:52:08 +0100 (BST)

So the fact that it's come in from a dialup connection is 
fairly buried.
