问题：
如何为特定用户组在离开网络的电子邮件上标记页脚/免责声明？
许多组织都希望在邮件系统中的外发邮件上放置一个页脚。这样做通常是出于法律原因，例如向邮件添加免责声明或警告收件人邮件包含受保护的通信。在AsyncOS中，这称为“页脚印戳”。
页脚戳是一个不太精确的图画，通常仅用于外发邮件。 这是因为许多邮件具有复杂的结构，如HTML或Microsoft Word正文部分，并且在这些正文部分添加页脚可能是不可能的。页脚标记有两个步骤。 首先，创建页脚。 然后，使用三种方法之一将页脚添加到邮件中。
- 首先创建页脚。在GUI中，导航至Mail Policies -> Text Resources，然后点击Add Text Resource
- 创建一个没有条件的“传出内容过滤器”(Outgoing Content Filter)（因此，它将应用于邮件策略中的所有邮件），并使用您所创建的页脚执行“添加页脚”(Add Footer)操作
- 在策略中启用页脚标记筛选器。
提示：虽然可以在侦听程序上或使用邮件过滤器或内容过滤器执行页脚标记，但是对特定用户组执行此操作的最简单方法是使用内容过滤器。
还可以使用邮件过滤器添加邮件页脚：
AddOutgoingDisclaimer:
if (recv-listener == "OutboundMail")
and (mail-from == ("@exchange\\.example\\.com$") {
add-footer("Disclaimer");
}
您还可以向特定侦听程序上收到的所有邮件添加页脚。 例如：
