SpamKiller makes copies of all automatically filtered mail. It allows you to filter any part of a message, including the text, headers, and country codes. The friends list allows desired e-mail to reach you. The filter wizard makes it easy to add your own filters, and you can download online updates. It also allows you to automatically send complaints and error messages to spammers. It handles any number of MSN/Hotmail, POP3 and MAPI accounts. It can block all messages from senders not on your friends list. It supports Microsoft Network e-mail and extended MAPI.
