I do not know how exim, but I have here with postfix this in
/etc/postfix/Makefile

   neu: neu-prepare all

   ppp: ppp-prepare all

   ppp-prepare:
      cp -f main.cf.ppp main.cf
      cp -f sender_canonical.ppp sender_canonical

   neu-prepare:
      sed -e 's/surfbest.net/neu.edu/g' main.cf.ppp > main.cf
      sed -e 's/surfbest.net/neu.edu/g' sender_canonical.ppp \
      > sender_canonical

Then it is easy to create (courtesy of sudo) this script called
smtp:

   #!/bin/sh
   ( cd /etc/postfix ; sudo -u root /usr/bin/make "$@" )

and in the script run whenever your are checking emails this
(smtp.neu.edu is a SMTP server when I am connected through LAN
and in variable MYISP I have name of the currently active ISP --
American or Czech):

	if /sbin/ifconfig | grep -q '^ppp' \
		&& grep -q 'smtp.neu.edu' /etc/postfix/main.cf
	then
		smtp $MYISP
	fi

Does it help?
