Anyone know how to configure postfix to relay mail to anywhere, so long as it comes from a "trusted" user, because right now it only wants to relay mail to a "trusted" host. I don't want to make every host trusted by default, just able to have mail relayed to it.
Really, no idea how I did this, but hopefully you'll be able to decode something. Here's my config: http://conor.homelinux.net/main.cf
This is a config that will relay mail to any foreign address, provided the user logs in and is authenticated by SASL.
