Can I disable e-mail notification sounds streamed to a bluetooth hands-free car radio

**Is there a way that one can automatically turn off the email notification when one is connected to a bluetooth-enabled car radio, ie. while driving, and only respond to incoming call notifications?** Once the bluetooth connection is broken, the suppressed e-mail notifications should then be delivered. Alternatively, if the e-mail notification is sounded, the phone should not maintain a bluetooth streaming mode status to the hands-free kit and the radio should revert to whichever audio/radio mode was previously in use. The phone is from the Samsung Galaxy range.
