Using BIS to retrieve email from multiple accounts, my device keeps accumulating emails and never clearing any old ones automatically. This makes my device get sluggish until I go delete a bunch.
Under 'GENERAL OPTIONS ---> Actions' I have it set to "Keep Messages" for only 15 days, yet it keeps everything.
Is there a way to keep 15 days (or any other number) worth of messages and have the BB delete the older ones so it doesn't accumulate them?
