Enough people (2) asked for this that I've put it on a web page:
http://www.math.jhu.edu/~martind/debian/myexim.html
Be aware that these scripts relate to my setup and will NOT work
unless they're modified.  Mostly, any references to "cush" or to
"jhu.edu" need to be changed.

My exim configuration does this.

Assuming that you're using bo (aka Debian 1.3.1) you should do
something like this:
cp /usr/bin/pon /usr/local/bin/ponmail

Edit /usr/local/bin/ponmail and after the `cat /etc/ppp.options_out`
add "ipparam mailonly".

Then, put the following 6 lines into /usr/local/bin/poffmail:
#!/bin/sh
export PATH=/bin:/usr/bin:/usr/local/bin
while netstat --inet -n | grep ESTABLISHED > /dev/null; do
  sleep 5
done
poff

Then do:
chmod a+rx /usr/local/bin/poffmail

If you don't have the commands 'runq' and some sort of fetchmail
command in your /etc/ppp/ip-up then add the following two lines to
/etc/ppp/ip-up:
runq -qf
HOME=~myuser su -c 'fetchmail -d 900' myuser

(where 'myuser' should be your regular (i.e. non-root) username)

You should probably put a 'killall fetchmail' into your
/etc/ppp/ip-down script.

Now, at the bottom of your /etc/ppp/ip-up (AFTER any runq or fetchmail 
commands) put the following 4 lines:
if [ "$6" = "mailonly" ]; then
  sleep 5
  /usr/local/bin/poffmail &
fi

What this does: if you start ppp with 'ponmail' istead of 'pon', then
your machine will shut down the ppp connection as soon as there are no 
open connections.  Adding the fetchmail and runq lines to
/etc/ppp/ip-up causes your machine to deliver any pending mail and get 
any waiting mail each time ppp is turned on (with pon or with ponmail).

Yes; read the fetchmail man page.  The keyword you want is "keep".
