Hey Folks, Thanks in advance for any help you can provide. I think it might make the most sense to start by describing what I'm trying to accomplish first. Which is this, I have a server that is configured as the host for our mailman lists (lists.example.org), it also sits between postini and our exchange server and processes mail for aliases that point to other providers. So it should process anything for example.org and lists.example.org using it's local aliases file then pass it to mailman, our exchange server or to somewhere else.
So far so good, I've got it doing all that. The new wrinkle that I need help with is getting it to pass all outbound mail not destined for mailman or our exchange server back to postini for outbound processing. I think I'd want to set postini to be the Outbound mail relay, but still have the server pass mail to the exchange server directly and also to continue processing mail for lists.example.org locally and passing it to mailman. I think I can do this with transport maps? Will transit maps override the relayhost settings when appropriate? I have the O'Reilly Postfix book, but wasn't able to determine this using that resource.
