the dispatcher.cnf method applies to all incoming connections, where as my method (if you move a line up some) will only cause say rbl to be checked for mail coming from the Internet. Mine you can use to log the entries to your mail.log_current file and thus you could generate stats and the like. Its a matter of choice. the dispatcher was done as lots of people were asking to be able to do this but did had a difficult time understanding the complexity of the mappings. Which I still do not understand 100%, probably never will. :)
