Unlike Norton Anti Spam 2005 and Mail Frontier, SpamKiller doesn't fully integrate into popular e-mail clients. Although the software does create a toolbar inside Outlook and Outlook Express, clicking the button to, say, view all your blocked mail takes you to a separate McAfee application where you can view and rescue messages it blocked by mistake. You'll then have to wait until the next time you download your mail to get the previously rescued messages, an extra hoop other programs don't make you jump through.
