Guide Review - CA Anti-Spam 4 - Spam Filter
The most comfortable way to approve senders is having CA Anti-Spam scan your email folders, and especially outgoing emails for people you know. Adding senders manually or from the CA Anti-Spam quarantine is just as easy.
Optionally, CA Anti-Spam can send a challenging message to new senders. Replying to the challenge will approve them. This can be a bit annoying, though CA Anti-Spam is pretty smart about mailing lists and makes sure you get all list traffic if you approve one message. Spammers using commonly approved addresses (of popular newsletters, for example) can get through CA Anti-Spam's filtering, but CA Anti-Spam also supports sender authentication protocols and will warn you if somebody pretends to be somebody else. This also helps with phishing attempts if the spoofed sender has implemented one of the authentication schemes.
In my tests, CA Anti-Spam did not use DomainKeys authentication, though. CA Anti-Spam also helps you with all the good mail you do want to get. A real-time index of all your messages (and other data such as contacts or to-do items) lets you search fast, easily and with precision right from CA Anti-Spam's toolbar.
