What I do, Swimpy, is sort by "From", with "Subject", "Size", and "Time Recieved" in the succeeding columns. I do have a "Whitelist" folder that automatically gets stuff from certain senders I have "preapproved", such as freinds, family (well, some of 'em anyway
), business contacts, and subscribed alerts and newsletters, but the rest goes through the manual "look-decide-keep-or-delete" process. Most absolute junk is readily identifiable, with a little experience, through particulars either in the "From" or "Subject" line. I use Select + Shift to highlight and delete huge blocks of the crap at a time. It really takes just a few minutes to do.
