Re: [outages] Blackberry Email Troubles?
You've obviously had more experience with BIS services than I. So, I'll default to you on that. I did use Sprint's BIS service 2 years ago for a very short time. I had the option of specifying a check time of no less that 15 minutes. I have not bothered to keep up on BIS services as it's of no use to the company I work for. But, if IMAPIDLE is all you need to call something push, then by all means call BIS a push service. However it lacks a lot of the sync features and control that we get from our BES environment. All of which you stated previously (Calendar and Contacts) along with a whole slew of logging and management features that we get from having our devices managed by a BES environment. Message delivery time may be exactly the same. One may be slower depending on a whole slew of factors outside of the device itself. If you experience a service quality above what blackberry has in their KB articles. I would think that you are experiencing the upside of the BIS service. But I wouldn't expect RIM to jump if you were experiencing delays of up to 15+ minutes. I know from talking with RIM that they even expect a delay of up to 10 minutes from email server to device to be acceptable because of the different variables that can impact the delivery. But, when I call them and tell them a group of users in an area are experiencing delays and I'm not seeing significant out of coverage messages in the log files. They're quick to get me an answer as to who, what, where and why. At the end of the day it's more about what is the preference for the Business. If all you need is email then I would say BIS is plenty good enough. Service response time may be completely the same from the user perception of it. On Monday, December 21, 2009, at 10:45AM, "Jay R.

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.

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).

What we have here is a failure to listen. Each carrier will assign you one (or more) "native" BIS mailboxes, within the blackberry.net domain, and attach them to your phone. Mail sent to those mailboxes will be delivered by the same "true push" protocol used on BES setups, as that's what BIS really is: it's a big-ass BES cluster. BIS customers can also configure IMAP pickup from off-net mailboxes, and I don't know whether that's proxied by BIS and pushed to the phone, or polled directly, cause we don't use that. That may or may not support IMAP IDLE. Cheers, -- jra -- Jay R.
