Dr.Web for Unix Mail Servers

Highly intelligent anti-virus and anti-spam protection system for large amounts of e-mail traffic


Meet highest security standards

Dr.Web for Unix Mail Servers is certified by Russia’s Federal Service for Technical and Export Control (FSTEC) and Federal Security Service (FSB) and, subsequently can be used in networks with high security requirements. Dr.Web for Windows meets all of the requirements of anti-virus products regarding the protection of personal information as stated by Russian law and can run on computers requiring maximum protection.

Flexible configuration

Dr.Web for Unix Mail Servers can be configured using rules providing greater flexibility compared with competitive solutions that can only be set up using static parameters in configuration files. Messages are filtered and modified according to established policies where the administrator can configure individual processing rules for different users and groups and even for each e-mail. It allows the product to meet any requirements to corporate security.

Low system requirements

The system requirements of Dr.Web for Unix Mail Servers are very low allowing it to run on any server hardware. It makes the anti-virus a perfect choice for companies that can't afford modernizing their server hardware on a regular basis to meet ever growing requirements of most anti-virus solutions.

Minimal TCO

Unlike many competitive solutions Dr.Web for Unix Mail Servers enjoys the most flexible multi-optional licensing. A customer buys only components they need and doesn’t pay for software they don’t need and will never use.

Perfect scalability

Dr.Web for Unix Mail Servers with its capabilities for processing huge amounts of data real-time, reliability and flexibility meets demands of small companies using one mail server as well as unlimited requirements of multi-national telecom providers for scan of mail traffic.

Rapid response

Multi-thread scanning ensures rapid response of the anti-virus allowing it to scan arriving data real-time along with files received earlier and to deliver e-mails to end-users without a notable delay.

Efficient filtering of unsolicited e-mails

Dr.Web anti-spam is shipped as a solution component (but never as a separate product). It is installed on the server where the anti-virus product resides. It simplifies administration of the solution and lowers its TCO compared with competitive solutions.

Additional advantages of Dr.Web anti-spam

  • the anti-spam doesn’t require configuration or training. Unlike anti-spam solutions based on Bayesian filtering, it starts working as soon as the first message arrives
  • It detects spam messages regardless of their language
  • Customizable actions for different categories of spam
  • The white and black lists of its own rule out a possibility for a company to be discredited by adding it deliberately to lists of unwanted addresses
  • Record-low number of false positives
  • Stays relevant with one update in 24 hours – unique spam detection technologies based on several thousands of rules allow the anti-spam to stay up to date without frequent downloads of bulky updates
Enhanced security for corporate mail

Dr.Web for Unix Mail Servers can be integrated with various mail servers, and it can also operate as an SMTP proxy server, filtering messages before they reach the mail server. Dr.Web for Unix Mail Servers and an additional SMTP proxy used simultaniously provide:

  • Better overall network security
  • Improved filtering quality with no limitations caused by a mail server
  • Lower workload of local mail servers and workstations
  • Greater stability of the mail filtering system
Protection of confidential information

The quarantine managed over the web-interface or by means of a special utility and the option for archiving all e-mails transferred through the filter allow tracking causes of data leaks and restoring messages accidentally deleted by users from their mail boxes.

Guaranteed delivery of e-mail

Guaranteed delivery of all messages makes configuring a mail server easier. Even if a user is unavailable for a long period of time and can’t receive a message, it will be stored in a special directory.

Easy administration

The web-interface allows administering the product from any computer connected to the Internet.

These are not the only advantages of Dr.Web for Unix Mail Servers! Learn about all strong points of the product with our online testing service Dr.Web LiveDemo.

Enhanced security for corporate email

For maximum filtration quality, use Dr.Web SMTP proxy — a filter that processes email messages before they reach your mail server. When mail filtering is organised this way:

  • network security increases substantially;
  • the filtering quality is significantly improved due to the absence of any mail server restrictions;
  • the workload decreases for local mail servers and workstations;
  • the mail-filtering system’s overall stability improves.

The cost of an SMTP proxy license is only 10% of the cost of a Dr.Web MSS license.

Arguments for CEO | Arguments for the CIO

Dr.Web for Unix Mail Servers with its flexible configuration, reliability and its capabilities for load-balancing and real-time processing of huge amounts of data meets demands of small companies using one mail server as well as requirements of multi-national ISPs for scan of unlimited amounts of data.

Dynamic load balancing optimizes server performance without additional testing.

The configuration testing and service control interface enables on-the-fly configuration of operation of services which significantly simplifies system maintenance and allows its faster deployment.

Settings of the filtering service and quarantine can now be stored in storages of different types ranging from ordinary files to databases like Oracle.

LDAP directory services are used to store settings. It provides integration of the solution into the structure of the corporate directories service and makes administration of the solution easier.

Rules are added into the daemon’s configuration file — it is one of the most useful features of the software. Rules set in the mail daemon configuration file allow changing operational parameters of the mail daemon depending on the contents of processed messages. The current version of the mail daemon allows setting rules for sender and recipient addresses and for particular types of malicious objects found in messages.

Dr.Web for Unix Mail Servers can archive all incoming and outgoing messages allowing restoring accidentally deleted e-mails and determining how an infection spread over a network.
