The program is based on Bayesian filtering technology, so it automatically learns using your personal correspondence to increase filtration accuracy. Quarantined e-mails are stored in a separate spam folder. Users can manage friends and enemies lists, or build their own filters. POP3, IMAP, HTTP and MS-Exchange protocols are supported. The program has an option to test outgoing mail for potential risk of being filtered as spam. Recognition of newsgroup messages using Safe Recipients list and automatic inclusion of outgoing mail recipients into Friends List are available.
