FastMail - Now with Personal Bayesian Spam Filtering

Holders of "Full" and "Enhanced" FastMail accounts now can get even more precise spam filtering by using personal data for Bayesian analysis.
You can mark individual messages as spam or good mail manually to teach the filter, but it will also learn automatically over time (albeit a tad slowly) from messages otherwise found to be spam. An interface still in beta allows you to define spam learning actions per folder.
›› FastMail is a great free email service with IMAP access, useful features, one of the best web-based email interfaces and few ads.
