How can I change the default sender address of my hosting server?

I use the php::mail() function in my scripts to send out emails from the server. While I can change the From header, the sender still shows as a default address from the hosting server (something@server.thehost.com)

Where in the cpanel settings can 开发者_如何学PythonI change this address?

Thanks.

Try using the fifth mail() argument: '-f your@sender.address'
