Configuring email (PHP Mail) with Craft
Does Craft require any specific configuration for PHP Mail to work?


No.  Craft assumes that PHP's mail function is already working if that's what you've selected under Settings->Email in the control panel.

You don't mention what the actual problem you're having is (i.e. getting an error message or email not being delivered, etc.), but there is a support article here that can help you debug both of those issues: https://craftcms.com/support/troubleshooting-email-errors
