Cement defines a Mail Interface, as well as the default DummyMailHandler that implements the interface as a placeholder but does not actually send any mail.
Cement often includes multiple handler implementations of an interface that may or may not have additional features or functionality than the interface requires. The documentation below only references usage based on the interface and default handler (not the full capabilities of an implementation).
The default dummy mail handler simply prints the message to console, and does not send anything. You can override the mail handler via App.Meta.mail_handler, for example using the SMTP Extension.
Creating a Mail Handler
All interfaces in Cement can be overridden with your own implementation. This can be done either by sub-classing MailHandler itself, or by sub-classing an existing extension's handlers in order to alter their functionality.
