[EAS] email configuration for Gmail?

[Cody Wilson]

Alex - 

This sounds like the Hub Transport role Exchange servers are in a DMZ, which is not a bad place for them.  That said, if your IT department has employed stateful firewalls between IP zones, you should still be able to talk to the Hub Transport servers and communicate via SMTP to them.  If they've completely eliminated IP connectivity to the Hub Transport servers except through the Mailbox Store Exchange servers, then unless you can convince a network admin to make an exception for you and allow traffic between your EAS appliance and the Hub Transport servers, or spools up another Hub Transport server that you can have IP access to (which is highly unlikely given the cost of doing so), you're out of luck as far as using your internal mail servers.  

Your Android phone likely talks to Exchange over ActiveSync, which is essentially MAPI over HTTP(S).  Google licensed ActiveSync connectivity for Android, as well as deployed ActiveSync servers for Gmail/Google Apps.  That's why you get "free" access to ActiveSync enabled mail servers on your Android phone.  If you're not, then you're constantly routing to the public Internet to access your Exchange account over IMAP/POP3 and SMTP.
