Hello, I am attempting to get Postfix working as a relay to an Exchange 2010 server in the same subnet. The incoming mail may originate from the same subnet, but it all goes through a central server that is outside the subnet. I am doing this for troubleshooting connections between the central server and the Exchange server, so it is only temporary.
The outside server would route mail through the server running Postfix, which would then relay to the Exchange server. To get the results that I want, without planning for a permanent setup to relay to Exchange, what Postfix configuration parameters do I need to set? These are the parameters that I am guessing have to be tinkered with and I have added some values, but am unsure about if I need to do anything with the others. Since I don't want mail to be delivered locally on the Postfix server, I am assuming that mydestination should be empty? mynetworks relay_domains = $mydestination, ip.of.outside.mailserver mydestination = (empty) myorigin relayhost = [exchange.server.ip] Thanks for getting me started in the right direction. -- Christopher Adams adam...@gmail.com
