before_save.php

class myClass{

    public function myMethod($bean,$event,$arguments){

        // if we are using a legacy API or web-to-lead form, email address is in email1
        $GLOBALS['log']->fatal("email1 value: {$bean->email1}");

        // but if we're on that sugar7 API or sugar7 interface (which uses said API...)
        $sea = new SugarEmailAddress();
        $email = $sea->getPrimaryAddress($bean);
        $GLOBALS['log']->fatal("sea value: {$email}");

        $GLOBALS['log']->fatal("Request: " . print_r($_REQUEST,true));
        return;
    }
