Anti Spam Filtering

SpamTrap Listing updated: January 28, 2005

SpamTrap is a managed, server-side antispam and antivirus service. It uses a multi-stage process to identify as much spam as possible while not losing legitimate emails. To implement an in-house, business-grade antispam system requires an IT staff that has knowledge in this area and the purchase of related software and hardware. By using managed services, such as SpamTrap, an organization can free up valuable IT resources and save on the upfront IT costs.

TrueProtect Listing updated: January 28, 2005

FrontBridge utilizes three layers of protection to analyze each piece of email and to detect and act on suspected spam.
Blacklisting: FrontBridge uses a proprietary blacklist. We do not use commercial blacklists such as MAPS and ORBZ/S. Our blacklist contains only the addresses of the most egregious spammers on the Internet. While conservative, our blacklist can immediately block nearly 10 percent of our customer's inbound spam.
Fingerprinting: Messages not blocked by blacklisting are fingerprinted to detect matches with known spam message characteristics. FrontBridge's fingerprinting technology leverages knowledge gained from filtering mail for our entire customer base.
Messages identified as spam are fingerprinted and given a unique id based on their content. If these messages come through our system again, the fingerprint is detected and the message is marked as spam.
Rules-based scoring: FrontBridge assigns scores to messages based on more than 20,000 rules that embody and define characteristics of spam and legitimate email. Points are added to the score if a message contains characteristics of spam; and points are subtracted if it contains many characteristics of legitimate email. When a message's score reaches a defined threshold, it is flagged as spam.

White Mail Listing updated: January 28, 2005

Designed to use a combination of filtering mechanisms White Mail does not rely on static rules that are stale and ineffective. But instead uses mechanisms to trap and trace incoming spam and viruses. White Mail is a complete email filtering solution. Designed in the ASP format, White Mail catches and stops unsolicited email before it ever reaches your network. Unwanted email can be archived to a folder for later perusal, forwarded to a Postmaster email address or simply deleted.
