Each routing group in your enterprise will have an Internet Mail Connector running on a specific server. Using ESM go to your routing group and on the General tab of the Internet Mail Service (servername) there is a tick box to "Forward all mail through this connector to the following smart hosts" and give it the IP(s) of your Smart Hosts. The Smart Hosts can be any type of SMTP box, Exchange, *nix, ZIX, you name it. I believe this is what your looking for. From what I remember reading when setting up our Zix servers a couple years ago, if you have more than one IP listed in that field it will attempt a "round Robin" while sending. Looking at outgoing logs it seems that one of the Zix servers is busier than the other, so it may not be a true round robin, rather may have a busy timeout on it.

If you have a single server that's your dedicated outgoing Internet mail server, how do servers in other routing groups throughout the enterprise know to forward outgoing messages to it? Does the Connection Scope setting in the Internet Connector do the job,r do you need to put a smart host on the other SMTP connectors, or is it something else? I'm hoping someone who definiitively knows the answer will chime in. Thanks.
