Guide Review - McAfee SpamKiller 5.1 - Spam Filter
McAfee SpamKiller doesn't achieve that, but it tries to. SpamKiller uses a flexible filtering engine and comes with a large number of powerful filters that quarantine detected spam immediately. But spam continually evolves, and so does SpamKiller. SpamKiller downloads new filters and updates automatically.
Of course, you can review SpamKiller's decisions and rescue mail or manually delete unwanted mail off the server. Unfortunately, the former is necessary a bit too often. SpamKiller's filters spot a lot of spam, but they are overzealous.
While it is easy to add senders to the white list (SpamKiller even monitors your email client's address book to add new contacts automatically), this should not be the only method to avoid false positives. McAfee says SpamKiller uses Bayesian filtering, but unfortunately you can't train the filter with messages you rescue.
It's easy to set up sophisticated filters (either to delete or accept certain messages), though, and the filter sensitivity can be reduced from the default "high". This and disabling the hidden-text filter help.
You can also submit spam — why not false positives? — to McAfee for filter improvements. And complaining about spammers more or less correctly is a snap in SpamKiller.
All in all, McAfee SpamKiller makes a nice, but not necessarily precise anti-spam tool.
