170 Kaspersky Internet Security 7.0
13.1. Selecting an Anti-Spam
sensitivity level
Kaspersky Internet Security protects you from spam at one of the following levels
(see Figure 59):
Block all – strictest level of sensitivity, at which only messages containing
phrases from the phrase white list (see 13.3.4.1 on pg. 179) and senders
listed on the white list are accepted: everything else is marked as spam. At
this level, email is only analyzed against the white lists. All other features all
disabled.
Figure 59. Selecting the Anti-Spam security level
High – a strict level that when activated raises the likelihood that some emails
that are not spam will be marked as spam. At this level, email is analyzed
against the white and black list, and also using PDB and GSG technologies,
as well as iBayes (see 13.3.2 on pg. 176).
This level should be applied in cases when there is a high likelihood that the
recipient’s address is unknown to spammers. For example, when the
recipient is not signed to mass mailings, and does not have an email
address on free/non-corporate email servers.
Recommended – the standard universal settings level for classifying email.
At this level, it is possible that some spam will not be detected. This shows
that Anti-Spam is not trained well enough. You are advised to conduct
additional training for the module using the Training Wizard (see 13.2.1 on
pg. 172) or the Spam/NOT Spam buttons (or corresponding menu items in
The Bat!) for emails that were incorrectly marked.
Low – the most loyal settings level. It is recommended for users whose incoming
correspondence contains a significant number of words recognized by Anti-
Spam as spam, but is not spam. This may be because of the recipient’s
professional activity, which forces him to use professional terms in his
correspondence with colleagues that are widespread in spam. All spam
detection technologies are used to analyze emails at this level.
