Is there a way to filter email such that I only receive email on my Blackberry from one particular sender?
Thanks

Yep... Set your filters up so the Default is not to forward emails to your BB. Then set up one filter using the email address you want delivered to allow emails through.

This is what I tried: phone/options/email filters
then; "If not filters apply, send emaiml to handheld" =NO

and have a filter using the one email address. Something's not right. It didn't work.
