SpamSquash is a spam filter for email clients that connect to pop3 email servers. It uses two filtering methods: a Bayesian filter and a DNS block list. The Bayesian is trained by you to get emails you consider to be spam. The DNSBL uses spam repositories to determine what is spam. The filter is over 99% accurate. It also includes a white list and a black list. You can use one filter or both filters together. You can use it with Outlook, Outlook Express, Pegasus Mail, etc. You can download a free trial version at www.alwayslearn.com.
