Hi, This may or may not be what you are looking for. If you have a dedicated machine with lots of IP addresses then I would do LXC[1] (Linux Containers) on it. This way you can have completely different rules on each postfix. Your containers will act as if they were different physical machines. HTH, Mikael [1] http://lxc.sourceforge.net/
