Archive messages
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. | | Output to DVD storage
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. |

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. | | Backup of Archive
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. |

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. | | Journal Account
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. |
Audit Trail
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.

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) |
RPM Installation
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. |
Vmware installation
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. |
Windows Virtual Server installation
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.
