What is UbeBlock
UbeBlock is an innovataive approach to the problem of identifying and removing spam (Unsolicited bulk email) emails from your network.Traditional anti-spam measures work by trying to find specific words and phrases, look at how the message headers have been created, or see if any number of other little oddities have occurred in the message.
UbeBlock is different, it is a learning system that bypasses all of this and instead concentrates on the one thing that the spammer cannot hide, his message. All spam has one thing in common, it has to tell you its message. UbeBlock is designed to concentrate on the message.
How it works
UbeBlock uses a sophisticated probabilistic density algorithm to determine the likelihood that the message is spam.
After UbeBlock had determined the probability that the message is spam a flexible set of rules can be used to determine what to do with the message. In addition UbeBlock allows the user to specify a set of "Safe Words" that, should they occur in a message, will prevent the message being treated as spam. Whitelists can be used to idenitfy users or domains who should bypass the filters and the mailing list and contact database can be included in the whitelist eliminating the need for the administrator to maintain the whitelist.
Simple operation
When in operation, UbeBlock is almost transparent to the users. If they receive a message that is spam but was not filtered correctly they simply send the message to a specific UbeBlock training address and in future similar messages will be trapped. Similarly if a message was filtered incorrectly it can also be sent to training so that similar messages will not be identified as spam in the future.No longer do system administrators have to painfully examine messages for key phrases or symbols as UbeBlock does it for you.
The analysis engine of UbeBlock makes it hard for spammers to find a route round it. It can decode base64 message, it can untangle complicated HTML obscuring tricks, if the spammer has a message he wants you to read then UbeBlock can identify it.
Real Time BlackHole Lists (RBL)
Integration with "rbl black hole lists" allow UbeBlock to determine if the message has been passed through any known "open relay" sites on the internet (sites known to source or freely relay spam). The user can then specify how such messages are to be handled by UbeBlock.SPF bypass
The filtering system can be configured to bypass messages that come from SPF validated domains.
