Dr.Web has selected the best technologies and created a comprehensive Anti-spam solution for you!

Client-independent solution
Dr.Web Anti-spam does not require mail program plugins in order to function. Deep integration into Dr.Web SpIDer Mail monitor means the software runs completely independent to any e-mail client(s) used for receipt and processing of e-mails.
F-i-l-t-e-ring of e-mail traffic via POP3\IMAP4
The incoming mail is F-i-l-t-e-red, not only on standard POP3 protocol but also on the popular IMAP4. IMAP4 allows users to download parts of a message such as the subject, body, attachment, etc, instead of the whole message. This helps save on traffic as well as lets users view messages marked as spam allowing them to choose not to download these unwanted emails.
Highly efficient F-i-l-t-e-ring
The anti-spam was primarily designed for corporate mail servers and so has a high F-i-l-t-e-ring speed. In one second Dr.Web Anti-spam checks over one hundred messages for spam on-the-fly (1.9GHz Pentium 4 CPU)! In addition, Dr.Web Anti-spam will never overload your computer and has little effect to the timing of email receipt.
Different technologies for different types of spam
Dr.Web Anti-spam uses different F-i-l-t-e-ring techniques for different types of unsolicited e-mails - such as spam, phishing, pharming, scamming – and bounce messages, this technique produces an exceptionally high detection rate.

Before a verdict is made - spam\not spam - the collective features of each message are studied.
F-i-l-t-e-red mail is not deleted!
Messages marked as spam are never deleted. Spam messages can be automatically sent to a designated folder and checked/deleted at a later date.
Regular updates
Spammers invent new techniques every day to counteract spam-fighters, as do Dr.Web anti-virus and anti-spam developers. Like anti-virus, anti-spam requires frequent updates.
