The two Blackberry options are BES and BIS. BES (Blackberry Enterprise Server) is housed locally (but could be hosted) so it is not a problem. BIS (Blackberry Internet Service) can be accessed from the device or the web. In either case the user creates an email account "object" that has the user name and password for the remote account. BIS uses this info to pull the email from the remote account and push it to the device. So while the user may believe the password it stored on the device it is not. -Eric Eric Case, CISSP eric (at) ericcase (dot) com http://www.linkedin.com/in/ericcase (520) 344-CISO (2476)

Universitycredentials
used by third parties I haven't looked closely at Blackberry -- perhaps I need to? The scenarios I'm aware of are: 1. User sets their institution email to forward to a remote address -- in this case their Blackberry address. No exposure of credentials unless
they
want to reply (or originate) on the device and have those messages go through our outbound servers.... 2. User configures personal device to download messages from their institution inbox. Does either of these actually involve sharing the user's credentials
with
the *service*, beyond their device? I had assumed not, but now I'm not so sure....

password
policy.They did this specifically because they get flooded with "how do I save my email" requests when we deactivate email accounts, but other users take advantage of it as well. Yet, when we propose the idea of officially embracing this Gmail-IMAP-sync option as a more reliable alternative to forwarding - essentially treating Gmail the same as any other IMAP client - the idea is immediately shot down because it violates password policy.What was the violation? The problem that users woud need to store a password, likely the regular one, at gmail in order to use imap? We ended up with a convoluted system to avoid some of those issues.
