Auto generated temp addresses (Score 1)

I created a simple script to generate temporary email addresses that I can use to post on the web. I send an email to [e-mail] and qmail sends me an email address that forwards mail to my normal address in a form like [e-mail] my crontab removes the aliases that are older than 7 days. Very convenient and works nicely. Coincidentally, Yahoo mail added this type of feature at about the same time I did.
