CONFIGURING THE CHANNEL ACTION MATRIX
Each Preprocessor module has a Channel Action Matrix. The Preprocessor uses the Channel Action Matrix of a module to
determine when and to which messages it will run the module. The Channel Action Matrix appears as a table with the
leftmost column containing the different input channels (i.e., LOCALOUT,
SMTPD, BSMTPIN,
DLOUT,WEBCLIENT) and the topmost
row containing all the output channels (i.e.,LOCAL ,
SMTPC , BSMTPOUT ,
DL ).
You can configure the Channel Action Matrix on this page.
NOTE: The cc:Mail and Notes channels are displayed when Internet Exchange for Linux is installed and running in a cross-platform distributed environment.
To configure the Channel Action Matrix, do the following:For example, you wish all mail coming from the Internet destined to your local users to be scanned for viruses. What you need to do is to configure the Channel Action Matrix of the Anti-virus module to run on messages that flow from the SMTPD channel (channel where messages from the Internet pass through) to the LOCAL channel. To do this, you simply need to tick the check box in the Channel Action Matrix where the SMTPD and LOCAL channels intersect. The check mark will indicate that the Anti-virus will run on messages that flow through the SMTPD-LOCAL channel combination.
If you do not wish to run the particular module on your messages, you may leave all the check boxes unmarked.
