In Exchange 2007, can I configure one Hub Transport for internal mail and one for External?

Posted on 2007-09-29

This question comes about because in 2003 we had to send a mass-mail to about 1000-2000 agents, In doing so, it created 7000 messages totalling about 2.25GB to transmit (needless to say it took about 10 hrs to actually transmit all of that!)

So in 2007, since I have multiple hub/client access servers (2) is it possible to configure one of them to handle only internal mail traffic and then to configure the other one for external? That way, my internal mailflow isn't affected while sending one of those mass emails out?

    Yes and No

    by deafult you hub has 2 recieve connectors Client and Default this will handle internal mail at the moment.

    Hub are random in selection unless you have the hub role on the mbx server in which case that hub will be used

    by default the recieve connectors are not configured to handle inbound mail, permissions have to be modified

    On the hub you want to handle internet mail you will create a new Recieve connector for inbound and Create a Send connector that is hosted by this server.
    Now you have a machine that handles internet mail, however it could still be choosen to handle internal mail.

    ATIG, so if I follow you correctly, with my 2 Hub/CA boxes, I leave one as it is to do internal mail, and then create the receive connector on the second one to receive mail, but how does exchange differentiate between the two, or can it?

    My mbx role is on its own as well, no hub on it.

    Permissions...... The recieve connector from the internet will be for anyomous and not Exchange server...

    You can look at the default connector tabs....

    but you will still have the default connector handling internal well.

    I know there is a reg hack to force to a particular hub

    ATIG-do you have an article or something that explains the permissions in greater detail? It's not so prevelant right now, but in about a month or 2 I will have everyone migrated to 2007 and would like to have it configured as such.
