So either RIM feels they should have this, or they're really stupid.
There is no reason to send your email credentials to RIM ... the local device needs it, but I can't think of a single defensible reason to send your credentials to their servers.
Why do companies feel they're entitled to this kind of information? Pretty much everyone who owns a BlackBerry should be asking if they can really trust the device.
Looks like you have no clue how RIM e-mail works on Blackberries. Just copy and pasting a quick summary on how their e-mail system works.
"Unlike other PDAs, the BlackBerry device does not log into your email account for you, and check for new messages. This pull type email is best related to having a Post Office box. It requires physical action on your part to go and check your mail. You have to get up, drive in your car to the PO Box location, open it up, check for new mail, get back in your car, and drive home. All this time you are expending time and energy. What happens if you are unable to check the box due to the store/post office being closed? You have to wait until the next chance you get, and then check. As you can see this is not a very time/energy efficient way of doing things.
On the other hand, if you had someone to bring your mail to you, a Postal worker wouldn’t that be a better alternative? All you have to do is sit at home and when the mail arrives you have it. No need to do anything, no need to go anywhere else. This is how the BlackBerry architecture works." (Example From Crackberry.com
For a site apparently loaded with Computer professionals its astounding how many here do not know how BlackBerry e-mail works.
