AntiSpam Multiple Defense System for SendMail Server Blocks e-Mail Spam On Three Fronts; Protects Against Mistakenly Rejecting Real Mail.

Verification response e-mail security system minimizes false

positives and gives organizations a reliable, virus-resistant, easy

means of blocking automated junk e-mail

New and important E-mail messages arriving from outside sources now can be processed without fear of rejecting them as unwanted junk e-mail, thanks to a new mail server software add-on from SYSTEMSLOGIX which delivers multiple techniques to stop automated junk e-mail.

AntiSpam, installed on SendMail mail servers, blends a filtering program, algorithms and verification response. This three-tiered multiple defense also minimizes worries about rejecting desirable e-mail. When AntiSpam requests verification from a sender, automated spammers will rarely confirm their desire to send a message. However, legitimate senders can easily confirm by typing and returning an AntiSpam "passkey word" provided by the AntiSpam server.

Acting like a firewall, AntiSpam is administered by an Internet Service Provider (ISP) or an organization's IT department. It enables the server to reliably block automated junk e-mails before they enter the users' inboxes. Unlike the variety of filter-only spam control systems now marketed, AntiSpam saves administrative time by eliminating the task of looking for legitimate e-mail which has been mistakenly flagged as junk. The system features verification response which places the burden of verifying e-mail messages on the spammer or the legitimate sender.

"Small or mid-sized businesses, universities, hospitals and government operations face an onslaught of highly suspicious e-mail, just like larger corporations do, yet they do not have the time, IT resources or software budgets themselves to maintain an expensive spam blocker," says Dennis DiCosola, co-owner and technology director of SYSTEMSLOGIX. "AntiSpam uses multiple techniques to help administrators stop spam easily and affordably."

AntiSpam helps keep administrative overhead low by using an automated, multi-step process:

   --  An e-mail arrives at the mail server, where AntiSpam regularly
       checks all incoming messages.

   --  AntiSpam comprehensively checks several criteria to determine
       whether the sender of the e-mail message is approved to send
       e-mail to the address.


   --  If a sender's e-mail address is on the organization's
       "Approved" or whitelist, the e-mail message is sent to the
       inbox. Administrators and users can pre-authorize senders such
       as legitimate contacts, vendors, customers, clients and those
       delivering messages to a mailing list on which the
       organization has agreed to reside. Files can be uploaded to
       AntiSpam containing all approved contact e-mail addresses.

   --  If a sender's e-mail address is on the "Blocked" or blacklist,
       the e-mail message is rejected.

   --  If the arriving e-mail is the sender's first e-mail to the
       organization, AntiSpam returns a verification e-mail. The
       sender must reply to in order to complete delivery. The sender
       must copy a special "passkey word" to the subject line of the
       return message. This prevents automated systems which send
       spam from authorizing themselves.

   --  If any sender fails to verify their address within the time
       set by the administrator (usually five to 10 days), the server
       will reject the e-mail message. During this time,
       administrators and users can view and manually authorize
       messages using AntiSpam's user Web site.

   --  Once a sender verifies, the original e-mail message is
       forwarded to the inbox and the sender's addresses is added to
       the user's whitelist. Each e-mail address need only be
       verified once.

   --  Whenever checking e-mail, users benefit because AntiSpam's
       blend of spam filtering, algorithms and verification response
       results in users receiving virus-free e-mail messages from
       approved senders only.

E-mail programs compatible with AntiSpam include Eudora, Outlook, Outlook Express, Netscape, Entourage, Mail for Mac OSX and any program supporting the POP3 Protocol. Users can access the system via Microsoft Windows(R), Mac OS(R) and Linux(R) operating systems running standard Web browsers and POP e-mail programs.
