I have had much success decluttering my BB inbox by filtering several senders from coming to my BB. I have been unsuccessful at filtering those sent to "undisclosed-recipients," which is usually exactly the type of group list email that I don't need filling up my BB inbox.
I've tried putting "undisclosed-recipients" in the "Sent to" field and have also tried various combinations of checking and unchecking the "sent directly to me" "CC: to me" and "Bcc: to me" buttons.
Hmmm... I did a quick search and didn't find a way to do this, other than a "keyword" filter. I'm not familiar enough with BES to know if this would work or not.
