Spam Filter

Stop Spam and Viruses before they even come close to your Network.

The Spam filter automatically eliminates "junk" e-mail or "Spam" from each users mailbox, protecting workers from unwanted distractions and interruptions. With the ever-increasing amount of unsolicited e-mail arriving daily, protection is an important means of saving time and staying focused on important work at hand.

As e-mail passes through the mail routers, our proprietary Spam filter automatically scans inbound e-mail and separates out any Spam found.

Spam is filtered in a multi-step process. The first step is a collection of millions of "bait" e-mail addresses. These e-mail addresses are used to actively look for Spam. Spam is captured and run through a process in which a fingerprint is created and added to a master database for each message.

Next, as each new customer e-mail message enters the E-mail SecurityNET^TM network, it is fingerprinted and cross-reference in the database to see if there is a match. If there is a match, the message is marked as Spam. If there is no match, the message proceeds to the next step in which it is run through a series of tests where different aspects of the message including the header, subject, and content of the message are analyzed. These tests give the message a score that in turn determines if the message is Spam. Spam messages are fingerprinted and added to the database. Clean messages are queued for delivery to the client. This process, on average, takes less than a second to perform.

Administrators have many options in regards to the filtered Spam:

• SpamTank: With the most popular option being the SpamTank, Spam is held in a user level quarantine on the Global Gateway or the Local Messaging Router. As Spam is identified, temporary junk e-mail boxes are created for each user. Users are notified that they have junk e-mail on the server and are given a link to a web-based control panel where they can check it. The administrator sets the notification interval. Spam is held in this user level quarantine for 30 days before it is deleted.

• Redirection: This option allows administrators to redirect all Spam to a single e-mail address. For example, Spam@yourcompany.com

• X-Header: This option allows administrators to insert an x-header. Rules can be written on the destination mail server to reroute mail via the x-header variable.

• Subject Line Modification: This option allows administrators to modify the subject line of Spam messages. For example, the word JUNK or SPAM could be inserted before the subject so that the individual users could easily identify Spam messages.

• Deletion: This option quarantines and deletes all Spam messages.

Virus Filter

The Virus Filter detects and eliminates viruses before they enter your network. The system utilizes several leading enterprise-class anti-virus engines. Integrated at the application level, the network receives virus definition updates every 10 minutes. All e-mail as well as attachments are scanned through our engines insuring the most complete protection possible. Our anti-virus partners maintain global research and solution centers to ensure viruses are identified as early as possible and solutions are implemented as quickly as possible. The anti-virus libraries are updated far more frequently and more efficiently than is possible within a typical company.

Benefits:

• No maintenance windows or downtime, causing the reduction in corporate protection
• Implementation in minutes with a simple change in DNS configuration
• Greater e-mail network security with seamless layers of anti-virus protection
• Stops viruses at the gateway level before they enter the company network, eliminating the possibility of accidental outbreaks
• Significantly less expensive than maintaining an in-house virus solution
• No staff training required
• Reduced load on IT staff and mail servers
• Easier to implement than any other anti-virus alternative
• Immediate updates to protect against fast moving virus outbreaks

Attachment Filter

The attachment filter is positioned to reject messages with certain types of file attachments before they enter your current messaging infrastructure. This feature insures potentially destructive files, such as ".vbs", ".scr", ".exe", etc. do not gain access to the customer's network.

Administrators can add or delete file types as well as file names in order to fine-tune the filter. Messages with blocked attachments are sent to the quarantine for administrative review.

Benefits:

• Dangerous files can be restricted and quarantined, making the work place safer
• Preventative layer of protection that is far less expensive than maintaining your own onsite filter system
• Filtered messages delivered to quarantine for review
• Reduced load on IT staff and e-mail servers
• No staff training required
• Easier to implement than any other alternative
• Potential bandwidth savings

Content Filter

The content filter gives administrators the ability to block messages based on words or phrases found in the message subject, message body as well as any attachments. Messages can also be filtered based on character sets (i.e. language types). Any filtered messages are delivered to quarantine for administrative review.

Benefits:

• Ability to maintain full control of e-mail
• Far less expensive than maintaining own content filtering system
• Reduced load on IT staff and mail servers
• Filtered messages delivered to quarantine for review
