installed. This could include scanning for correctness of HTML tags, font
size, or hidden characters.
You can enable or disable each of these stages of the analysis.
Anti-Spam exists as a plug-in for the following email clients:
• Microsoft Office Outlook (see 13.3.8 on pg. 186)
• Microsoft Outlook Express (Windows Mail) (see 13.3.9 on pg. 189)
• The Bat! (see 13.3.10 on pg. 190)
This option is only supported for the 32-bit builds of Microsoft Office Outlook and
The Bat! for computers running Microsoft Windows XP Professional x64 Edition
and Microsoft Windows Vista x64.
The task panel for Microsoft Office Outlook and Microsoft Outlook Express
(Windows Mail) clients has two buttons, Spam and Not Spam, which can
configure Anti-Spam to detect spam right in your mailbox. In The Bat! there are
no such buttons: instead the program can be trained using the special items
Mark as spam and Mark as NOT spam on the Special menu. In addition,
special processing parameters (see 13.3.1 on pg. 175) for spam are added to all
the settings of the email client.
Anti-Spam uses special self-training iBayes algorithm, which allows the
component over time to more accurately distinguish between spam and accepted
email. The data source for the algorithm is email contents.
Situations arise when iBayes is unable to classify a certain email as either spam
or accepted email to a high degree of accuracy. These emails are marked as
potential spam.
In order to reduce the number of emails marked as potential spam, you are
advised to conduct additional Anti-Spam training (cf. Section 13.2, p. 195) on
such emails. To do so, you must specify which of those emails should be marked
as spam, and which as accepted.
Emails that are spam or potential spam are modified: the markings [!! SPAM] or
[?? Probable Spam], are added to the subject line.
The rules for processing spam or potential spam emails for Microsoft Office
Outlook, Microsoft Outlook Express (Windows Mail), or The Bat! are specified in
special plug-in components within the email client itself. For other email clients,
you can configure filtration rules that search for the modified subject line
containing [!! SPAM] or [?? Probable Spam] and move the email to a
designated folder. For more information about the filtration mechanism, please
consult the documentation for your email client.
