He's only correct for BIS accounts that are set up to *poll* external mail servers at all. For accounts on the BIS itself, ie "@vzw.blackberry.net", it's true push, and for several reasons, that's the only way I configure my users. Cheers, -- jra ----- jlsparks@gmail.com wrote:
Actually he's correct. If you'll take a look at the BIS product docs at blackberry.com you will see that BIS-E does indeed poll non-preferred mail servers every 15 minutes. If mail is found, another poll is conducted 3 minutes later. This continues until no mail is found on the server, at which point the polling timer resets to 15 minutes. Of course, gmail, blackberry.net and other preferred providers act as true push (like BES), but pure BIS on a non-preferred mail server has a 15 minute poll.

Blackberries route all BES data over Rim's network and has a connection to your internal BES server(s). The major difference is that BES offers a much lower response time (push) and ability to sync Calendar and Contacts as opposed to the BIS service which I was under the impression was just a 15minute pop/imap refresh.
You've been misinformed. :-)
BIS email is instant-push, just like BES: my average delay is about 4 seconds.
You don't get calendar and contact sync, though; they have to have *some* way to sell BES server besides remote wipe (which you also don't get).
