BitDefender AntiSpam for Mail Servers 1.9

BitDefender AntiSpam should not be installed along with BitDefender for MS Exchange 2003, BitDefender for MS Exchange 2000 or BitDefender Antivirus & Antispam for Mail Servers (WIN SMTP Proxy), because all these products already provide both antivirus and antispam protection.

IPMatch
This feature matches a specific e-mail address to a specific IP. Thus, spoofed e-mail headers are no longer enough to fool a white list. If the IP address doesn''t also match, the message is rejected.

Keyword Filter
A content filter is implemented "before" the AntiSpam filter. Relevant categories are message subject, headers, body and address fields. A set of explicit allow/don''t allow rules must be defined. If and only if a particular piece of mail passes through the content filter does it reach the AntiSpam filter.

WBL (White List/Blacklist) support
This quite simply means that the admin can set a list of trusted and untrusted addresses from which to respectively "always accept" or "always reject" mail.

Charset Filter
The Reject char sets option will cause all the e-mail messages written in Cyrillic and/or Asian char sets to be rejected.

URL Filter
Most of the spam messages contain links to various web locations (which contain more advertising and the possibility to buy things, usually). BitDefender has a database which contains links to these kinds of sites. Every time you perform an update new links will be added to the URL filter; this will help increase the effectiveness of your AntiSpam engine.

Heuristic analysis technology
The heuristic filter performs a set of tests on all the message components, (i.e. not only the header but also the message body in either HTML or text format), looking for words, phrases, links or other characteristics of spam.
