and i would also suggest considering the nice multi-instance docs too: http://www.postfix.org/postmulti.1.html http://www.postfix.org/postfix-wrapper.5.html http://www.postfix.org/MULTI_INSTANCE_README.html makes things conceptually very simple, and then you can either merge instances, or split an instance(s) off to some other box(s)... May provide an easy, step by step, method to replace your old system, and each, doing a simple function, may be easier to debug... just like small, concise program functions are easier to grok than some massive main() with goto's. :) ..Otto
