'Full blown' home server's already working. G'zillions of solid tutorials on THAT one.

It does and will exist on the local server. So I was looking at the http://www.postfix.org/ADDRESS_VERIFICATION_README.html#recipient to have postfix "do it for me". Which I think is the right place. > For your home server, start here: > http://www.postfix.org/STANDARD_CONFIGURATION_README.html#local_network Yep. > You'll also want to set the VPS as relayhost, and set some controls > so the home system accepts mail ONLY from the VPS -- easiest way to > do that is add the VPS IP to the home system mynetworks, then add > something like this to main.cf: > smtpd_client_restrictions = > permit_mynetworks > reject Okay.

No idea of my my own which is better, so I'll stick with the "likely won't need" for now. > your future spam filtering config. As much as I can I'd like to KISS (but effective), use a good set of RDBLs and avoid amavis. Its config just befuddles me. Thanks! Gornle
