Intego Personal Antispam is the ultimate spam-fighting tool for Mac OS X. Personal Antispam analyzes your incoming e-mail, determining which messages are spam and which are valid messages, and does so in many ways: by checking a whitelist and blacklist of addresses, message headers, content or layout, URLs in messages, and much more.
Spam is the scourge of the Internet. Almost every Internet user receives spam: undesired e-mail messages selling products and services, messages suggesting that users visit certain web sites, often pornographic, and scams of all kinds. Some people get so much spam that they spend more time sorting their inboxes than they do reading legitimate e-mail; it is not uncommon to receive hundreds of spam messages each day, for only a few dozen legitimate e-mail messages.
