I have PHP 5 running on a hosted ISP. The ISP gives me minimal configuration options via cPanel. Is there any way to use email notification to respond to some given event? I want to send from PHP in the background. Must I specify environment stuff like POP or SMTP? My hosted ISP offers email addresses of course -- does using one of those make things easier? Now that you know how ignorant I am, do you have any general advice on approaching this?
