UBE Filters and the UBE Plug-In

The UBE plug-in is an SMTP plug-in to Netscape Messaging Server. SMTP plug-ins are dynamically loaded software modules that access the Messaging Server Plug-in API, an application programming interface. The plug-ins function by intercepting incoming and outgoing messages, analyzing them for certain characteristics, and taking appropriate action before possibly passing them on.

You access UBE filters from the Configuration Tab/Services/SMTP/Plug-ins/UBE on the Messaging Server Console.


 

UBE Filter Syntax

A UBE filter is a single text line containing 3 to 5 parts, in this order:
[:label] messageFieldmatchCriterionaction [argument]
Here is an example filter that includes all five parts: 
:DontSend Subject "Bad mail" REJECT "Do not send mail"
This filter (named "DontSend") will filter out all messages with a Subject line containing "Bad mail", and will reject the message with the reply "Do not send mail".

The Messaging Server Console gives you an nice interface into writing your own UBE filters.  You'll see how an actual UBE implementation with the Console works in the exercises on the following pages.
