AGAVA AntispamServant is a trainable filter featuring message content analysis. AntispamServant is characterised by high-speed and efficient operation with all e-mail clients, and does not require them to be specially adjusted. AntispamServant is analysing the spam and non-spam message samples you provide, developing sorting algorithms on the basis of the user’s criteria and constantly updating the whitelist, which ensures almost 100% efficiency in identifying unwanted mail. AntispamServant does not delete e-mails identified as spam messages but moves them to a separate folder. You can check the contents of the folder any time later instead of checking new received messages every minute. The spam filter is devoid of the problems common for the majority of baesian filters. AntispamServant: - applies a complex formula to deduce the summarized spam coefficient of the e-mail messages, thus preventing the problem of short-cut calculation; - accounts for the human error factor in the course of the training process and provides opportunities for subsequent correction; - is protected from over-training, as it is trying to classify e-mails before analysing them as samples; - uses an HTML parser to prevent the influence of common HTML tags on e-mail classifications; - identifies functional parts of speech and excludes them from calculation, so as not to degrade the quality of filtering; - can successfully classify e-mails even on the basis of short headers containing 2-3 words only. Other advantages of the program are that there are no restrictions on the number of mailboxes being filtered and that you can simultaneously use any other spam filters. AntispamServant supports POP3, IMAP and SMTP. This antispam program automatically identifies and supports SSL-connections.

AntispamSniper for The Bat!

AntispamSniper for The Bat! provides a bullet-proof anti-spam & anti-phishing protection for your mailbox. The unique combination of several methods for automatic email classification shows impressive filtering quality. Features: The statistical trainable classification algorithm has unique characteristics. It learns your private correspondence, extracts the distinguishing features from messages of different classes and uses that information for effective analysis of other incoming messages. The algorithm improves its classification quality continuously with each new learned message. The messages from whitelisted senders are not filtered by other methods and recognized as non-spam at once. The whitelist is updated on learning automatically. The filtering rules are recognizing spam and ham by specific combinations of symbols in a body and headers of the email messages. The rules are optional, because the trained algorithm and a whitelist are very effective. But the accurately assembled lists of rules may improve the classification quality in cases when the algorithm is unable to select a certain class for a message with high probability. Exceptions are the empirical conditions for filtering. For example, large messages are probably non-spam. The presence of certain types of attached files also can be a good sign for recognizing message as non-spam. Most phishing attacks are blocked automatically. The filtering log allows you to track back the history of classifying messages and training the plug-in. See the statistics of filtering as a table or as a nice chart. Both The Bat! and Voyager are supported.

AntiSpamWare 2.0, the new tool from the Webmastertools family, has hit the news - in the positive sense. AntiSpamWare, the software for identifying and eliminating unwanted advertising mails, recently found itself the star of the show on WDR, a German regional television station. The new program with its unique capabilities was featured in "angeklickt", the computer news section of "Aktuelle Stunde", a regular evening news show. Jörg Schieb, the presenter of "angeklickt", stated: "I don't know of any other program at present that is more effective, or more easy to use, in getting rid of spam mail. But AntiSpamWare is not just a filter like many others that are able to eliminate junk mails more or less automatically; it can do a lot of other things as well." Following the show, the software was downloaded by over 45,000 viewers. No other program is so fast, easy and efficient at separating the good news from the bad. In Version 2.0, AntiSpamWare is the only tool worldwide that can now clear unwanted mails not just from POP3 mailboxes but also from AOL™ mailboxes. For people and businesses with their own websites, but also for all other users as well, viewing incoming emails can be an arduous and time consuming business, as the interesting contacts are often buried in a flood of automatically generated spam. AntiSpamWare is able to recognize and delete unwanted mail; in addition, however, it also offers a whole range of interesting capabilities to stop it being sent in the first place. For instance, it allows complaint mails to be dispatched to the senders of junk mail and their Internet providers, so helping to stem the flood of advertising mails over time. The press about AntiSpamWare: The c't magazin describes the features of AntiSpamWare 2.0. The article can be read online. The german PC Magazin writes about AntiSpamWare in issue 09/2002 on page 21.

Babastik's AntiSpam Personal

The no nonsense, no compromise solution to stopping unsolicited email from cluttering your inbox. For Microsoft® Windows 98/Me/NT/2000 and XP. AntiSpam Personal uses what is called a White-list with Challenge and Response validation to stop emails from forged or invalid email addresses from reaching your inbox. It works with all email programs that access standard POP3 email servers: Outlook, Outlook Express, Eudora, etc. * No messing with filters or alternate email addresses * Stops SPAM, and only SPAM at the server * Prevents hackers from spying on your email when transferred to and from your email server * Runs automatically in the background * Simple setup How does it work? AntiSpam keeps a list of all email addresses you correspond with. Any email from a source not in that list of familiar email addresses is sent a verification email to verify the email is from a legitimate email user. Since 90% of spam is sent from bogus or unmonitored email addresses these emails will never be verified and will be automatically deleted from your email server by AntiSpam. Features: * Automatically searches your existing address book to figure out who you have corresponded with so that they never see a challenge message when emailing you in the future*. * Listserver/Automated email aware. When correctly tagged by the sender, listserver and bulk emails are not challenged but rather flagged and eventually deleted if not wanted. * One button installation for Outlook and Outlook Express users. * Tracking of statistics and access to consolidated statistics from all AntiSpam users. * All processing is done on your local computer. Information about emails and addresses never leave your computer. * Automatically uses the latest industry standard encryption when exchanging information with your email server, regardless of whether your email client came with it or not.
