    Alright, so reviewing http://advosys.ca/papers/postfix-instance.html as
    linked from the postfix webpage it appears in order to run multiple complete
    instances I need to make full copies of the config directory as well as
    separate out the spools. Is this still the preferred method? I ask this
    because I am trying to separate 30+ IPs and 30+ configs/spools may be a bit
    tedious to work with.
