Additional information Anti-spam technologies Dr.Web Anti-spam technologies consist of rules that can be divided into several groups: •—a technology that empirically analyzes all parts of a message: header, message body, and attachments, if any. •—a technology that detects evasion techniques adopted by spammers to bypass anti-spam filters. •—a technology that compares messages containing HTML code with a list of known patterns from the anti-spam library. Such comparison, in combination with the data on sizes of images typically used by spammers, helps to protect users against spam messages with HTML code linked to online content. •—a technology that compares the words and phrases of a message (both visible to the human eye and hidden) with words and phrases typical for spam using a special dictionary. •—a technology that filters scam and pharming messages including so-called “Nigerian” scams, loan scams, lottery and casino scams, and false messages from banks and credit organizations. •—a technology that detects bounces that are delivery-failure messages sent by a mail server. Such messages are also sent by a mail worm. The bounces are detected as unwanted. Processing mail by spam filter SpIDer Mail adds the following header to the processed messages: •X-DrWeb-SpamState: <value>, where <value> indicates whether the message is considered by SpIDer Mail as spam (Yes) or not (No). •X-DrWeb-SpamVersion: <version>, where <version> indicates Dr.Web Anti-spam version. •X-DrWeb-SpamReason: <spam rate>, where <spam rate> includes a list of evaluations on various spam criteria. You can use these headers and the prefix in the Subject field, if selected, to configure email filtering for your mail client.
To improve performance of the spam filter, you can report to Doctor Web errors in spam detection. If you find an error in the spam filter: 1.Create a new email and attach the message that was processed incorrectly.
