Feature and Technical Overview - BlackBerry Internet Service

email message encryption for integrated email accounts

The BlackBerry Internet Service encrypts email messages that it sends and receives using SSL if the external messaging server (POP over SSL, IMAP over SSL, or Microsoft® Outlook® Web Access) supports SSL encryption. External messaging servers use a standard TCP connection if an SSL connection is not supported.

instant messaging encryption

The BlackBerry Internet Service encrypts instant messages that it sends and receives over the SSL connection that the BlackBerry device uses to connect to the instant messaging server, if the instant messaging server supports SSL encryption

encryption of login credentials and changes to personal information or login credentials

Subscribers with a user name and password protect their data with a password when they log in to the BlackBerry Internet Service web site. The BlackBerry Internet Service is designed to encrypt login credential information from the BlackBerry Internet Service login web page using SSL and sends it using HTTPS. This encryption is designed to protect user names, passwords, and other BlackBerry Internet Service account information from unauthorized access. This encryption applies to login credential changes that the subscriber submits after logging in to the BlackBerry Internet Service web site.

protection from spam email messages

The anti-spam system for the BlackBerry Internet Service uses a reputation scoring system for IP addresses to evaluate the relative reputation of IP addresses of incoming email messages. If the anti-spam system determines that the email message is a spam email message, the anti-spam system blocks the email message before it can reach BlackBerry Internet Service subscribers.

For additional control of spam email messages, subscribers can create email message filters to file unwanted email messages or to prevent email messages from being delivered to their BlackBerry device.
