摘要： A method for applying policies to an email message includes receiving, by an inbound policy module in a protected network, message metadata of an email message. The method also includes determining, based on the message metadata, whether receiving the email message in the protected network is prohibited by at least one metadata policy. The method further includes blocking the email message from being forwarded to the protected network if receiving the email message in the protected network is prohibited by the metadata policy. In specific embodiments, the method includes requesting scan results data for the email message if receiving the email message in the protected network is not prohibited by one or more metadata policies. In further embodiments, the method includes receiving the scan results data and requesting the email message if receiving the email message in the protected network is not prohibited by one or more scan policies.

摘要翻译： 将策略应用于电子邮件消息的方法包括：通过受保护网络中的入站策略模块接收电子邮件消息的消息元数据。 该方法还包括基于消息元数据确定是否在受保护网络中接收电子邮件消息被至少一个元数据策略所禁止。 该方法还包括如果受到受保护的网络中的电子邮件消息被元数据策略所禁止，阻止该电子邮件消息被转发到受保护的网络。 在具体实施例中，如果在受保护网络中接收到电子邮件消息不被一个或多个元数据策略所禁止，则该方法包括请求电子邮件消息的扫描结果数据。 在另外的实施例中，该方法包括接收扫描结果数据并且如果在受保护网络中接收到电子邮件消息不被一个或多个扫描策略所禁止，则请求电子邮件消息。
