I have a script in /etc/ppp/ip-up.d that modifies/replaces my exim.conf
when I connect.  There are probably other/better ways to do it but it
works for me so I am sticking with it for now.

#!/bin/sh
# get the dns name of the dynamic ip
set name=`nslookup $PPP_LOCAL | grep Name | cut -c 10-`
# update exim config file 
sed -e s/--Name--/${name}/g /etc/exim.conf-up >! /etc/exim.conf

Then at the top of exim.conf-up I have the following,
 
primary_hostname = --Name--

I got this idea from the Dynamic-IP-Hacks mini-HOWTO.  I also do the
same type of thing with /etc/hosts and my cfingerd setup.
