[EAS] email configuration for Gmail?

The entire mail system is handled by the state of MN system, so i'm
sure there's some very asinine policies in place. Like i said, i know
that if the originating connection is internal (on the 199.17.x.x/16
block) SMTP is disabled. If i do it externally, SMTP/SSL/TLS is
employed for connections back to the servers on campus.
I believe that Google/Android did license ActiveSync like you
mentioned, but there are other implementations in the wild as far as
MAPI support (think third party Android images, evolution mail
program, etc). If there's enough codespace in the Sage ENDECs or not
to handle it, who knows. Probably not.
Native Exchange support should be an item on a lot of this gear. Most
radio/tv stations use Exchange/SBS as well, not to mention most public
stations who rely (like me) on the university network. I understand
the coding nightmare it brings with it, but like it or not, this is a
Microsoft world still.
The best part of this whole adventure is, before 2005, the university
used Unix/BSD. They had 3 mail servers handling all users running on
Sun gear. Barely broke a sweat. Now they spend millions on maintaining
a Microsoft system that makes all the users jump through hoops and
purchase more software. Go figure.

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.

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.
