Chilkat BlackList ActiveX v2.0.1 | 843KB BlackList provides the ability to instantly determine if an email contains a domain name contained in a blacklist. The blacklist can be very large, and lists of over 1 million domain names are easily handled with instant lookup times. Chilkat BlackList also un-obfuscates both HTML and plain-text email bodies and quickly parses out domain names from all parts of the email to check against a blacklist. Spammer obfuscation tricks are reversed, and domain names are returned in a canonicalized form for easy recognition
