Server-Based Anti-Spam Software Listings

This section contains a list of anti-spam software for servers that are installed either on the mail server itself or in front of the mail server. Therefore gateway-based anti-spam solutions are also included here.

Such solutions normally perform spam identification and filtering before legitimate emails are distributed to the intended recipients throughout the network thus reducing the impact that spam has on end-user productivity and on network resources. Because of the server-based approach, anti-spam and general email content policies are easily enforceable throughout the network, but usually at the expense of flexibility for individual users.

Some solutions allow users to review mail on the server which has been flagged as spam and give them the opportunity to notify the network administrator of any false positives. The network administrator can then fine-tune the software for improved accuracy.

Many of the solutions listed here are comprised of various modules that address issues such as email anti-virus protection, anti-trojan protection and enforcement of outbound email corporate policies, providing enhanced value for those that require an all-in-one solution.

Vorras Classifier
Vorras Classifier is a server-side email anti-spam tool that relies on machine learning technology to distinguish between spam and legitimate email messages. Decisions on incoming emails are based on a database residing on the email server that is updated on a regular basis.

MailBoss scans all incoming, outgoing and internal messages, and disassembles even the most complex attachments. It finds viruses, unapproved file types and undesirable content. It checks compliance of all e-mail traffic with the Information Security Policy. Filtering is performed on headers, body, MIME attachments, etc. Based on the results of the analysis, e-mail can be delivered, delayed, quarantined, and archived. If desired, an e-mail administrator or other authorized person can be notified automatically. The intelligent content-filtering engine is the unique feature of MailBoss. It can utilize the most complex and sophisticated rules and policies.

Automatic pattern-matching technology used in most other e-mail filters leads to a significant number of false alarms, and at the same time, can lead to the loss of over 30 per cent of important messages, just because of the presence of a “forbidden” word. It makes competitors’ systems very unreliable. Unlike other content-filtering solutions, MailBoss uses an Intelligent Categorization Module. It uses full-text analysis algorithms, which take into account not just the words alone, but the whole context. Using already stored data, it makes much more intelligent decisions, thus increasing the reliability of the filters, and significantly reducing risks of loss of valuable information.

Lyris MailShield Server
Lyris MailShield Server is a server-based email filtering program for medium- and large-sized businesses. MailShield Server can be used to block spam (junk email), prohibit mail relaying, and prevent mail bomb attacks – among many other email-related tasks! MailShield Server’s “fuzzy logic” filtering engine is one of the most effective spam-blocking tools available on the market. The engine supports the SpamAssassin spam identification technology, which runs over 300 separate tests on each individual message. As each test runs, MailShield Server allocates points to that message – the more points, the greater the probability that an individual message is spam. Depending on the result of these tests, MailShield Server can mark, redirect, or bounce undesirable mail.
