Spamgate Technology:

Spamgate Email Protection
	Email is as important as the telephone for communications between your customers and your company. The constant bombardment of spam and virus attachments quickly causes your email server to bog down. The Spamgate Firewall is an integrated hardware and software solution that has the power, ease-of-use, and is the most affordable solution available to solve this growing problem. The Spamgate Spam Firewall appliance includes all the features needed to eliminate your spam and completely protect your email server from all forms of attack. Email may be blocked, quarantined, tagged, or delivered based on the policies of your company. You can even customize an individual email address as needed for special employees. If a message is detected as spam, SpamGate can take the following actions: • Store the message in the SpamGate quarantine folder for user review • Automatically delete the spam message • Modify the subject line to indicate “Spam” for individual filtering • Modify the message header for individual filtering • Forward the spam message to a common mailbox • Reject or bounce the spam message back to the sender

Key Anti-Spam Technologies
SURBL Module SURBLs differ from most other Real Time Black hole lists (RBLs) in that they're used to detect Spam based on message body URIs (usually web sites). Unlike most other RBLs, SURBLs are not used to block Spam senders. Instead they allow you to block messages that have Spam hosts which are mentioned in message bodies. The SURBL module also helps detect the phishing type of messages.		Distributed Hash Databases Vipul's Razor, Pyzor and DCC are collaborative spam-tracking databases, which work by taking a signature of spam messages. Since spam typically operates by sending an identical message to hundreds of people, these databases short-circuit this by allowing the first person to receive a spam to add it to the database -- at which point everyone else will automatically block it.
Real Time Blackhole Lists We support the popular Real Time Blackhole lists (RBLs) that can be selected via our management interface. Examples: Spamhaus, Spamcop, MAPS, ORDB-RBL, SORBS, CBL, RSL.		Open Source SpamAssassin Engine Heuristic spam engines examine the behavior of email traffic down to the packet level to determine if it is spam or not. Heuristic engines, through non-linear mathematics, identify a message as spam by correlating the results of various spam filters that are triggered by an incoming message. Only if sets of related filters specific to spam are triggered, at the same time, is the message classified as spam. A true value of the heuristic engine is that it becomes more refined and efficient as it processes more and more email.
Greylisting Can block SPAM for a specific mailbox or all mailboxes Greylisting is a new method of blocking significant amounts of spam without resorting to heavyweight statistical analysis or other heuristical approaches. Consequently, implementations are fairly lightweight, and may even decrease network traffic and processor load on your mailserver. Greylisting relies on the fact that most spam sources do not behave in the same way as do “normal” mail systems. It works by requesting the senders mail server to resend a message. As the spammers will not typically resend a message, the original message will not be processed. Once a message is successfully received, the message will not be requested to be resent again.		Auto-Learning Bayesian Filter A technique used for identifying incoming e-mail spam. Unlike other filtering techniques that look for spam-identifying words in subject lines and headers, a Bayesian filter uses the entire context of an e-mail when it looks for words or character strings that will identify the e-mail as spam. Another difference between a Bayesian filter and other content filters is that a Bayesian filter learns to identify new spam the more it analyzes incoming e-mails. Bayesian filters are adaptable in that the filter can train itself to identify new patterns of spam and can be adapted by the human user to adjust to the user’s specific parameters for identifying spam. Bayesian filters also are advantageous because they take the whole context of a message into consideration.
Rules_Du_Jour SpamGate automatically retrieves antispam rules on a daily basis from an archive of rules to fight the latest spam attacks.		Anti-Virus Scanning SpamGate supports 15 different Virus Scanners but we typically use 2 default virus engines that are automatically updated every hour. The virus scanner also includes a module to detect phishing types of messages.
File Attachment Blocking SpamGate includes a file attachment blocking module which allows file extentions to be defined of specific attachments to be blocked.		E-Mail Address Validation Each recipient e-mail address can be verified against your messaging servers using LDAP or advanced technologies like Milter-Ahead. This will prevent invalid adressed messages from being sent to your mail servers, i.e., (Dictionary Attacks)
Keyword and Phrase Filter We provide a module for adding your own keywords and phrases to be checked in the subject line and body of a message should you need additional filter rules.		Management Interface A browser based interface that will display the color-coded status of each message to quickly determine spam messages in real-time. You can view the header information of the message as well as view the actual contents of every message.
Manage User Quarantine (Web Interface) Allows each user to check their Spam in the quarantine with a browser interface at any time and then release a message in the quarantine and whitelist the message.		Manage Administrator Quarantine (Web Interface) Allows the administrator to view all spam in the quarantine at any time for any period of time and then release a message in the quarantine and whitelist the message.
Whitelist / Blacklist Maintenance Allows you to control the sending addresses that you will automatically: forward mail from (Whitelist) and reject mail from (Blacklist). This method saves the processing time of your SpamGate appliance from having to scan the email and report a score. Instead it reads the sender’s information and automatically forward or reject the message based upon your arrangement.		Outbound Scanning SpamGate performs virus and spam scanning in both directions on the same appliance with a simple change to the SpamGate configuration.
Archive Module The Archive module will save a copy of selected messages or all messages to another mailbox.		Easy Installation There is no software to install. There are no modifications required to your existing mail system. All SpamGate's come pre-configured to your network needs. Just plug it in, and it will begin to scan incoming email immediately.
Increase Your Email Server's Capability The SpamGate Antispam Appliance is self-sufficient, meaning that it handles all your spam-blocking so it does not bog down your email servers. Consequently, the load on your email system will be dramatically decreased, since they will process and store less incoming mail. Therefore, the performance on your email servers will increase.		Automatic Updates to System As spam trends change, new updates to provide the maximum proficiency in detecting spam will automatically be performed on your SpamGate appliance. There is no need for your organization to do it manually. SpamGate proficiency will always be maintained.
Support for Multiple Domains & Email Servers All SpamGate models can be used no matter the number of domains or email addresses.		Detailed Message Reporting SpamGate maintains detailed statistics of Spam and Virus efficiency at your site. Reporting data provides you with key metrics to show the value of the SpamGate appliance as a filtering solution. Multiple reports are available, including filtering data on a recipient, sender, or IP address basis. For example, administrators can use these features to see which employees in their organization are receiving the most spam. View the screen shots for sample reports.
