Can I stop Mail from automatically marking emails as read (before I have read them)?

I'm sure I'm not the only one with too much email. I will often skim through the summary list, deleting some and moving some to junkmail. This gets rid of a lot.

But as I move or delete an email, my cursor moves to the next email in line and marks it read. I then have to click on it and mark it as unread.

Unless there's a crystal ball connected, Mail can't tell if I'm going to read the email. Can I get it to mark it read once I've OPENED it instead of when the cursor simply lands on it?
