With the default config (it says this somewhere in the INSTALL or README 
file btw), add an entry to the alias file for all system accounts you 
don't want to have mail delivered to. I use a custom message "Unknown user"

bin:            :fail: Unknown user
daemon:         :fail: Unknown user
user123:        :fail: There is no spoon

This will :fail: any RCPT TO that makes it to the alias router.

There is no need to change the system_aliases router.

Ted.
