OMPONENT OPERATION ALGORITHM
Anti-Spam's operation consists of two stages:
First, Anti-Spam applies rigid filtering criteria to the message. Those criteria allow a quick determination as to
whether the message is spam or not. Anti-Spam assigns the message the spam or not spam status, the scan
will be stopped, and the message will be transferred to the mail client for processing (see Steps 1 through 5
below).
whether the message is spam or not. Anti-Spam assigns the message the spam or not spam status, the scan
will be stopped, and the message will be transferred to the mail client for processing (see Steps 1 through 5
below).
At the further steps of the algorithm (see Steps 6 through 10 below), Anti-Spam analyzes email messages that
have passed precise selection criteria at the previous steps. Such messages cannot be unambiguously
considered spam. Therefore Anti-Spam has to calculate the probability of this message being spam.
have passed precise selection criteria at the previous steps. Such messages cannot be unambiguously
considered spam. Therefore Anti-Spam has to calculate the probability of this message being spam.
Provided below is a more detailed discussion of the Anti-Spam operation algorithm:
1. The sender's address is scanned for matches on black and white lists of addresses:
if a sender's address is in the list of allowed senders, the message will be assigned the not spam status;
if a sender's address is in the list of blocked senders, the message will be assigned the spam status.
