BB Software :: Using Pop Emails With Curve 8530

Had a BB in the past but never needed to use it with my 4 pop e-mail accounts. Just switched from HTC Snap to a new BB curve 8530 and it does not seem to do what I need it to. On the snap it would check for new messages from all 4 pop accounts hourly and when doing so any new unread messages on the pop server would go to the snap phone and any deletions that were made on the pop server were removed from the snap phone also. I am sure BB has a way to do this but I am not seeing where or how to set this up. So far it seems I have to delete it on my BB to delete it off both but it will not take deletions from the pop and remove them from the BB. I have so many e-mails I have to manage and it is making me want to go back to the Snap since this is causing a lot more work.

Also, is it normal for PDF files to take a while to load and become clear to view as e-mail attachments? I seem to be waiting a while in comparison to the snap I had prior.
