I'm trying to hook up to a Humble Widget that I'm using to sell our game, and we have created a backend that we want to invite users to when they buy it.
The best we can get from Humble is an e-mail notification when a purchase is made. I have set up a cron task to check the account's e-mail every 10 minutes and execute the appropriate response when it runs, but I don't like the idea of customers having to wait up to 10 minutes after purchase to get the e-mail.
I found this article about how to execute scripts with sendmail, but it doesn't seem to be working. Is this possible on Dreamhost servers? Possible at all on LAMP?
