if you're using pppd, then use the script /etc/ppp/ip-up, you'll find that
the IP address is one of the parameters passed to it, so you don't even
have to use ifconfig, you could just
echo ADDRESS=$4 | mail youraddress@work
though you'll have to check to see which parameter is the local address,
and change $4 to that number.
The only way I know to do this with ppp (user space) is with the cron
file, though I'm sure that someone can set up a better way of doing it, I
just don't use ppp enough to know the ins and outs.
