David, I can't help with the screen display, but I can with filtering or screening emails. I look at them on my iPhone. It has a much more efficient system than laptop computers. I can very quickly use the edit function to skim through the list if senders and subjects, delete in bulk the ones I don't want and either read and answer the others or close Mail on the phone and access the emails via my laptop. Preferences can be set so a bcc of any answers I send from the iPhone is sent to me, which means it's received and kept on my laptop.
Cheers, Michael Hawkins.
