Email data is pushed to the BB devices. You can set your email filters so that email is not delivered to your handheld. If you're running against a Blackberry server (corporate environment) v. .4.0 or higher, you can set this from the device. Open Messages, select Options from the Messages menu. Select Email Filters. Change the setting "If no filters apply, send email to handheld:" to NO. Set any filters/rules to not deliver to the device.
If you're receiving email through Desktop Manager redirector, set email filters through Desktop Manager -> Redirector Settings -> Filters.
You can ensure the settings are working while you're still within domestic coverage. Just send an email to yourself that would generally deliver to your BB. If you don't receive it, the filters are working properly. You would still be able to send messages while traveling internationally, so you'd just need to avoid the urge to keep from getting charged.
If you have any applications (3rd party to the default RIM components) that automatically push data to the device, set the settings within the individual applications or delete the apps. Reload when you return.
