Hello, I have just finished installing exchange 2010 in my Exchange 2003 environment. Since we only have a single exchange server environment, and a single static IP. How do I ensure internal, but more importantly, external connectivity? We have a sonic wall router, and I need to make sure that mail delivered goes to the correct server. Some mailboxes will be on 2003for the time being, some on 2010. I need to ensure auto discover, activesync, and outlook anywhere works. I should also note that all email is filtered through mxlogic, how do I make sure email is delivered to the correct place? Thank you!
