You can create or modify your a SMTP connector on your exchange routing group to direct all content to a smart host (which is your postfix server).

You address space should be "*" as you want all your traffic using that connector and assure that the cost is the lowest within your routing group.  Then you can specify this connector for your organization or just the routing group.

Try this tutorial on how to setup a SMTP connector in Exchange 2003.

I did see that. My Exchange server is already set up like that and forwarding to our postfix server. I'm wanting  Exchange to send all outbound mail to another one temporarily. Is that all I have to do is change the smart host in advanced delivery? Why are my options to start, stop the virtual smtp server grayed out? Additionally I get an error "the virtual server instance is not running when clicking on current session.

Thanks.

Do you have more than one connection under protocols->SMTP ?

Using Exchange manager on my PC leaves these options grayed out even though I'm an admin..weird. However when I view exchange manager on the Exchange server itself..they are not grayed out. So once I edit the SMTP smart host address to point to another postfix server...is it safe to say all I need to do is restart the SMTP virtual and not reboot the box itself?

just restart the smtp virtual, not the whole server.

Just being a member of 'Administrator' group probably isn't enough for that.
I alwsys RDP to the server for such things.

So what if I wanted to take the postifx server out of the email flow entirely and just send out to the internet..leave the smtp virtual server blank?

thanks again for you time.

Thanks again for your info and help.
