I have resisted getting a Blackberry until now but I am beginning to see certain advantages.

My problem is that I sometimes get as many as 300 e-mails a day. There is absolutely no need for most of these to be sent to a handheld receiver. I wouldn't want my Blackberry ringing every two minutes.

Is there any way to set up your Blackberry so that only certain messages get through to you while still maintaining your usual e-mail address?

If it matters, my cellular carrier is Verizon which is also my ISP.
