I was receiving over 100 junk e-mails per day using the High junk mail filter. I spent two hours going through a year of e-mails to ensure that every correspondent is in my Address Book. Then I switched to the Exclusive junk mail filter. This cut Input box junk e-mail to around 50 per day, but it should have cut it to zero. How is it possible to get junk mail? The programming is not even 101 level: e-mail arrives---get sender's e-mail address---compare with list of e-mail addresses in Address Book---if no match to list, put received e-mail in Junk E-mail folder. I just can't see how this can fail.

I looked at the sender address of dozens of junk e-mails, and none of them come close to the e-mail addresses in my Address Book. Is this another case of sloppy programming on the Mac versions of Office that Microsoft can't be bothered to fix?
