The problem with ifconfig is that it will tell you the LAN IP address your MAC is connected to.
I don't know what kind of programs there is on a MAC, but if you have at least mail, wget and a basic shell, and if you know how to code a simple script that you can send to your MAC (via ssh, ...), write a script that wget to a site that returns your current IP address (Current IP Check for example) and send this page to your email address.

Code:

#!/bin/sh
FILE=/tmp/ext_ip

wget -T3 -qO$FILE http://checkip.dyndns.org/

mail -s 'My MAC address' youremail@adress.com << EOF
$(cat ${FILE})
EOF

exit 0

I didn't test the script above, but I hope it can help you a bit
If you can send this script to your machine via SSH or anything else, set the executable flag and use cron (or similar on MAC) to execute this script every hour or so, you'll receive regular emails containing the current (external) IP address of your MAC.
