10.9.2.2 Channel-Specific Reverse Mapping Example

By default, the address reversal text database is used if the routability scope is set to the mail server domains. An example of a channel-specific REVERSE mapping table entry would be as follows:

REVERSE

   tcp_*|tcp_local|binky@macho.siroe.com    $D$YRebecca.Woods@siroe.com
            

This entry tells the MTA that for any mail with source channel of tcp_* going out the destination channel of tcp_local to change addresses of the form binky@macho.siroe.com to Rebecca.Woods@siroe.com

To enable channel-specific reverse mapping, you must set USE_REVERSE_DATABASE option in option.dat to 13. (Default=5.)
