1. We are using a smart host/email spam appliance for all outgoing & external incoming mail. Do I need to configure the default received connector to allow for Anonymous? Or can I just leave it alone?
2. This maybe a result of the existing 2003 server but I notice that we have a send connector already and it’s pointed to our email spam appliance. Do I have to create another send connector as we have a number of distribution lists that contain external SMTP addresses that our users send mail to. We also have some servers email alerts to internal IT staff via Exchange. Can we just use the existing connector?
3. In Hub transport Client & Default receive connectors, “networks” setting, I assume this means the Nic adapter on the hub transport server that will be allowed to receive email. And not which remote IP address the hub server receive email from. Meaning if i have 1 nic card and my nic is 192.168.92.x, it would receive email from that IP. And it won't matter what the source ip is.
4. Do I need to create a new email address policy or can I work with the 2 that’s been created by default from the migration?
5. I don’t use ISA or TMG 2010 but I do use a web/spam appliance to filter mail, do I need to change the authentication properties for owa web app or can I leave it as default?
