Not sure how to do this with exim, but with qmail you
would implement the special routing for *@aol.com with
a line in the control/smtproutes file, and some lines
in your network connection scripts to delete the smtproutes
file when bringing up the DSL line and echo

        aol.com:smtp.kc.rr.com

into the smtproutes file when bringing up the cable modem.

These scripts are where the configuration adjustment goes.

qmail-remote reads the config file every time it starts, so there's
nothing to HUP or anything like that.

Exim certainly has a facility for this adjustment, but it might
require a signal of some kind, to restart the queuerunners.
