Outlook 2003 already has the second box, called Junk Email, built in. Go to Tools > Options > Preferences and in the E-Mail section, click Junk E-Mail. Here you make one several choices.
Remember, whichever choice you make here, the filtering is done by a dumb robot. Some legitimate mail will end up in the junk box and some junk will end up in the regular inbox. So be sure to check your junk box carefully every day before emptying it. I keep my setting on Low and the preview pane disabled (so that possible malware-bearing mail is not opened). It is then so easy to do my own filtering -- to make my own decisions rather than depend on some dumb robot -- and delete what I wish as I look through my inbox. I get a fair amount of mail from ''safe'' sources I do not want to miss completely, but not all of whose mail I want to read. I filter these based on the subject line.
Personally, I would never check the box to automatically delete junk mail. Who knows? You may someday get an e-mail from an unknown rich relative who wants to give you a million ? or perhaps some other mail that may be less valuable, but still of some interest to you.
Another thing many do is set up a completely separate account with a different address. Give out one address only to your ?safe list? and use the other for all on-line operations; most (but not all) spam will go into the latter. You can then also filter each of these, but the percentage of false classifications will be smaller.
Hope this helps
Recently I read about setting up a second inbox that you divert all emails from your "Safe Senders" to. But now I can't find the article, of course. This way, the original "inbox" still gets any new spam that slips through the filters along with Non-Spam emails that aren't on the safe-senders list yet. I've tried to find a setting to do this and maybe it's a "rules" thing, but I import my email in from Hotmail and can't access the Rules section. Any Ideas? thanks
