如何為特定使用者組在離開網路的電子郵件上標籤頁尾/免責宣告？

許多組織都希望對來自其電子郵件系統的傳出郵件設定頁尾。這通常是出於法律原因，例如向郵件新增免責宣告或警告收件人郵件包含受保護的通訊。在AsyncOS中，這稱為「頁尾標籤」。

頁尾印章是一個相當不精確的藝術，通常只適用於外發郵件。  這是因為許多郵件具有複雜的結構，如HTML或Microsoft Word正文部分，在這些正文部分新增頁尾可能是可能的，也可能不可能。頁尾標籤有兩個步驟。  首先建立頁尾。  然後，以三種方式之一將頁尾新增到郵件中。

1. 首先建立頁尾。在GUI中，導航至Mail Policies -> Text Resources，然後點選Add Text Resource

2. 建立一個沒有條件的傳出內容過濾器（這樣，它將被應用到郵件策略中的所有郵件），並使用您建立的頁尾執行「新增頁尾」操作

3. 在策略中啟用頁尾標籤篩選器。

提示：雖然頁尾標籤可以在監聽程式上完成，也可以使用消息過濾器或內容過濾器完成，但針對特定使用者組執行此操作的最簡單方法就是使用內容過濾器。

還可以使用郵件過濾器新增郵件頁尾：

AddOutgoingDisclaimer:

if     (recv-listener == "OutboundMail")

and (mail-from == ("@exchange\\.example\\.com$") {

add-footer("Disclaimer");

}

您還可以向特定監聽程式上接收的所有消息新增頁尾。  例如：

smtp.scu.com>listenerconfig
