Website local, mailserver external

you must do the following steps:

1. add the domain to relay_domains
2. add a transport in form of domain.tld relay:[ipoftheremoteserver]
3. add a list with valid recipients to the relay_recipient_maps.

thats how we do spam checking for exchange servers (without ispcp)

First step I already tried. There is no relay_domains in the Postfix config when freshly installed. When adding it manually the Postfixserver doesn't accept mail at all. I'm sure there must be a way to solve this, but I do not know how. Can it be because something is missing? Is there a way you past a example main.cf in here?
