PHP 邮件功能不从 Gmail 地址发送

我正在尝试让这个联系表单正常工作，但它似乎无法发送标题说它来自 gmail 地址我觉得雅虎地址也在混合中不起作用的地址。这是似乎对此很重要的代码。如果主持人很重要，我在Dreamhost上。请告诉我。

            mail ($email_to, $email_subject, $email_message, "From: ".$email_from." <".$email_from.">");
        }

基本上，如果在表单上填写的contact_email（不包括代码，抱歉，我认为您不需要它，但如果您需要，请告诉我）是一个 Gmail 帐户，它似乎没有发送它，请帮助我解决这个问题。
