Hello list, I would like to to use my postfix implementation to relay mail from one specific host on the internet, to any address on the internet. The idea is that the external host will send name in my name, i.e. it will appear to come from my domain.
I can allow the specific IP address to use me as a relay, but I expect that there is a more reliable way to do it... Could you please advise what would be the preferred, secure approach to achieve this? Kind regards, Lucas
