IceWarp Server can use IceWarp Anti-Spam LIVE, an example of RPD (Recurring Pattern Detection) Technology, as part of its fight against spam.
A Real-Time Detection Center analyzes large volumes of Internet traffic in real time, identifying new Spam, Virus and Phishing outbreaks based on characteristic mass distribution patterns. Emerging outbreaks are usually identified moments after they are introduced onto the Internet.
This can significantly help in protecting your Users from bulk and spam emails.
As with other IceWarp Anti-Spam technologies, IceWarp Anti-Spam LIVE is used to adjust the Spam score of a message rather than to give a final judgment on the message:

This field indicates a spam score that is a limit for running IceWarp Anti-Spam LIVE. A message comes to IceWarp Anti-Spam LIVE with some spam score. In the Score non-spam messages, you set a score for messages that IceWarp Anti-Spam LIVE recognizes as OK. This score is added (it is a negative number) to the score that a message has when coming to IceWarp Anti-Spam LIVE. If the result is higher than the spam score set in the Anti/Spam – Action – Score required to classify message as spam field, it is useless to apply IceWarp Anti-Spam LIVE because the message will still be a spam. E. g.: You have the Score required to classify ... value set to 4. The message comes to IceWarp Anti-Spam LIVE with the score of 7. 7 - 2.4 = 4.6 This message will always have its score higher than 4 – it is useless to run IceWarp Anti-Spam LIVE. Another example: The message comes to IceWarp Anti-Spam LIVE with the score of 5. 5 - 2.4 = 2.6 IceWarp Anti-Spam LIVE is run. |
Score bulk and highly suspected virus messages |
Set the slider to an amount that will be added to the Spam score if IceWarp Anti-Spam LIVE reports the message as bulk. |
Score confirmed spam messages and virus messages |
Set the slider to an amount that will be added to the Spam score if IceWarp Anti-Spam LIVE reports the message is Spam. Given the proven reliability of IceWarp Anti-Spam LIVE it is recommended that this be set at 9 or more. |
Score non-spam messages |
Set the slider to an amount that the Spam score will be reduced by if IceWarp Anti-Spam LIVE reports the message as not Spam. The default value is 0 because reducing the score too much can result in False Positives – remember that LIVE is one of several technologies adding up to the overall score. |
|
NOTE: The IceWarp Anti-Spam LIVE engine is only called for messages which are not classified as Spam by IceWarp Server's other AntiSpam engines, according to the Score required to classify a message as spam setting in AS Action - General. |

NOTE: Some servers block external access to port 80, thus they need to know what address is for AntiSpam LIVE to free it up in their FireWalls. This information is in the ctasd.conf file (<InstallDirectory>/spam/commtouch): Server_address = Resolver%d.icew.ctmail.com Where %d is some dynamic number. |
