I did that for a while, and then my provider decided that people using catch-all e-mail addresses were causing their systems to store too much spam and stopped letting people use them. That left me in a slight bind as I had used well over 50 different e-mail addresses. I had switched to Gmail as my primary e-mail address, but hadn't bothered changing my accounts. Luckily, they allowed a very easy way to create forwarding addresses and basically set it up to forward 50+ addresses to one.
