SPAM Control
Developed by MX Logic for high-volume messaging environments,
our SPAM blocker provides the most comprehensive and effective spam-blocking
available - blocking up to 98.5 percent of spam and providing an
industry-leading low false positive rate (legitimate email marked as spam).
Unlike most spam filtering solutions, which use one or two spam-classification
techniques, our SPAM blocker aggregates the most effective spam filters and
techniques in the industry, currently leveraging the strengths of five
spam-fighting filters:
 | Bayesian—Statistical algorithms built by MX Logic
identify and quantify the possibility that an email message is spam.
| Heuristics—Thousands of proprietary rules of thumb
recognize characteristics of spam.
| Distributed Checksum Clearinghouses—Takes a checksum,
or fingerprint, of all email messages it sees, and places those fingerprints
in a database. If the database recognizes a large number of exact matches or
at least very similar fingerprints, then those fingerprints are likely to
indicate spam.
| Distributed Black Lists: Mail Abuse Prevention Services
(MAPS)—A real-time subscription service that maintains multiple lists of
known spammers to help gauge the likelihood of a message being spam.
| Domain Level Black and White Lists—Maintained by
Email4Schools, these customized lists detail sites, individuals or IP
addresses from which mail is and is not allowed. |
| | | |
Each of the five filters dynamically calculates the
spam probability of every message. Through an aggregation and analysis of these
spam-likelihood scores, the system provides an extremely effective method for
blocking spam and enables you to decide how SPAM should be processed. You can
quarantine the message, deny delivery or do nothing.
