Another option, which worked well for me, is to put the fetchmail and
sendmail commands in the ip-up script.  You'll want to run fetchmail in
daemon mode <fetchmail -d 300>, where you can specify how often to check,
and do a fetchmail --kill in the ip-down script.  On sendmail, you can set
the queue to run every 5 minutes while online <sendmail -q5m> (ip-up) and
then reset it to some large number that will make sure it doesn't run when
offline <sendmail -q 1w> (ip-down).

Check the man pages for the various option flags, and customize to your
liking.
