Traffic flow

We have a spam box that all email comes into. So I pointed that to our new
email server and now email is going to that box.

But how does exchange know how to forward email to whichever server the
users email box is on? I know that is in AD but I am not sure how it works.

THe bigger question is about traffic flow.

Right now most users are on the new box but that box is not able to send
email out to the internet because it isn't setup on the FW.

So how does it know to send the email to the other server which then can
send out to the internet using SMTP?
THe bigger question is where is it setup on how email gets out to the
internet and how do I update it for the new email server?

Incoming email will hit an Exchange server. That server will do a
lookup in AD to see where the mailbox resides and then send it via
SMTP to that server.

As for outbound mail. If you only want the original server doing the
sending you can create a Routing Group SMTP Connector and then set the
current server as the local bridgehead. Have a look at it, it's
extremely intuitive and simple, since you don't want to do anything
complicated such as domain specifics or scheduling etc.

I checked that out, thanks. So right now we have 2 ex servers, one of them
the new 2003 box I am also finished moving to and another at a different
site that is 2000, and the one I am taking down now.
Right now I have no smtp connector setup, so how does email go out then?
I do have the default smpt server running though, but that just handles
email going in right?
