Guide Review - WinAntiSPAM 1.18 - Spam Filter
The theory behind a challenge-response approach to spam filtering says that it's impossible (and not lucrative) for spammers to authorize their address (which they hardly ever hand out to begin with).
WinAntiSPAM applies this theory in a simple manner, relying on spammers never using an address they can validate since authorization happens by a mere reply. This is convenient, but the challenges can still be annoying, in particular for newsletter publishers. Conversely, spammers just have to use commonly authorized addresses in the From: line to get through.
WinAntiSPAM must be credited for applying its overall simple approach to the user interface as well (though the account configuration is a bit odd), which makes it quite easy to use.
