Linux Mail Server Security
Designed for integration with a variety of Linux-based mail systems, Kaspersky Security for Linux Mail Server delivers security, flexibility and ease of management in a single application that includes cloud-assisted technologies.
Kaspersky Security 8 for Linux Mail Server provides next-generation email protection from known and unknown threats, including spam, phishing and malicious attachments. This is accomplished by multiple layers of machine learning-powered security, including multi-factor heuristic, sandboxing and reputation system for emails and attachments, which also achieves an extremely low rate of false positives.
Multi-layered anti-malware capabilities
Improved! Advanced antivirus engine – cloud-assisted via the Kaspersky Security Network
Kaspersky Security for Linux Mail Server includes the latest version of Kaspersky Lab’s award-winning anti-malware engine. Furthermore, it receives real-time information from the cloud-based Kaspersky Security Network (KSN) – so you benefit from a Linux mail server antivirus solution that delivers even better performance in detecting and removing malicious attachments from incoming emails including exploits, unknown and advanced malware.
New! Web malicious URL filter – cloud-assisted via the Kaspersky Security Network
With real-time updates from the cloud, Kaspersky’s Web malicious URL filter blocks emails that include links to infected sites or malicious files.
Detection of malicious macros/ActiveX controls in Office files
Embedding malicious scripts into Office files is a popular technique used by extremely dangerous specimen such as ExPetr / Petya / NotPetya. Kaspersky Lab’s next-generation anti-malware provides effective protection against such threats.
Anti-spam and content filtering
Improved! Anti-spam engine
Kaspersky’s anti-spam engine includes two powerful technologies:
Enforced Anti-Spam Updates Service (EASUS) – which uses push technology, directly from the cloud-based Kaspersky Security Network, to deliver real-time updates. By reducing the ‘update window’ from 20 minutes to less than 1 minute, EASUS helps to protect against Zero-Hour spam and spam epidemics.
Cloud-assisted Reputation Filtering – can ‘rate’ suspicious emails, place them in quarantine and then recheck them when updated information becomes available. This helps to defend you against unknown spam – while also reducing the number of false positives.
New! Cloud-assisted anti-phishing
Kaspersky’s new anti-phishing module receives real-time updates from the cloud-based Kaspersky Security Network – for more effective detection and blocking of emails that contain links to phishing websites.
New! Mass mail detection
You can easily set policies to block unwanted mass mail from reaching your end users.
New! Anti-spam quarantine
Suspicious messages are placed in the anti-spam quarantine, managed from the web interface. These messages can be reviewed later.
New! Spam Confidence Level rating
For organizations using MS Exchange, the Spam Confidence Level (SCL) rating, which lets users define actions for messages according to SCL thresholds, is now included.
Improved character support
Supports internationalized (non-Latin) characters in email addresses.
New! Unicode domain spoofing detection
Kaspersky Security 8 for Linux Mail Server now detects messages containing Unicode spoofing, which uses Unicode symbols visually resembling proper characters used in legitimate mail addresses and URLs.
New! Multi-layered archive protection
Kaspersky Security 8 for Linux Mail Server now recognizes and blocks certain types of files within archives and compound objects, providing detection inside multi-layered archives widely used by scammers.
Integration with most popular MTAs – including Postfix, Sendmail, Exim and qmail
You can choose the method of integration, depending on your Mail Transfer Agent (MTA) – so you can integrate as a plug-in or a Milter API.
Anti-virus command line file scanner
The Kaspersky Anti-Virus On-Demand Scanner allows on-demand virus checking of objects – including directories, regular files and devices such as hard drives, flash drives and DVD-ROMs.
AMaViS (A Mail Virus Scanner)
Kaspersky Security for Linux Mail Server supports integration with Linux mail systems using the high-performance AMaViS interface.
New! Integration with Kaspersky Anti Targeted Attack Platform
Kaspersky Security 8 for Linux Mail Server can be integrated with KATA – Kaspersky Anti Targeted Attack Platform. After integration, the application can send copies of messages to KATA for scanning. Based on the results of the KATA scan, the application can then block individual messages.
Suspicious messages are placed in the KATA quarantine, managed from the web interface.
New! Integration with Kaspersky Private Security Network
For those organizations that cannot participate in Kaspersky Security Network (KSN), Kaspersky Security 8 for Linux Mail Server can now integrate with Kaspersky Private Security Network (KPSN).
After integration with KPSN, the application can use the KSN reputation databases locally, benefitting from the latest, globally acquired threat intelligence - without sending any data outside the organization.
At-a-glance monitoring and flexible reporting
New! Integration with Kaspersky Security Center
Kaspersky’s easy-to-use management console, Kaspersky Security Center, gives you the ability to monitor security for all your Linux mail servers – including clusters – from a single console. If a security incident occurs, the system administrator will automatically be informed about the affected server and the cause of the issue.
New! Support for help desk function
Help desk specialists can now access a user’s backup and personal blacklists / whitelists – via a standard web interface, without disturbing system administrators or end users.
The web dashboard provides an at-a-glance view of status and monitoring, including information about the most recently found malware.
Full support for SNMP (Simple Network Management Protocol)
SNMP support lets you monitor any type of event, using SNMP events and traps.
Web and CLI management
You can choose your method of application management – using the Web console or command line interface (CLI).
Detailed, flexible reporting in PDF format
Customisable reports help you to monitor and analyse your security and policies.
Administrators and document owners are informed about policy violation incidents – so immediate action can be taken.
Detailed information about all product actions is automatically recorded – to help you to identify the cause of a problem.
New! Expanded helpdesk capabilities

Better detection… improves user productivity
Kaspersky Lab’s Linux mail server security solution includes advanced spam detection technologies that help to minimise the number of spam messages that get through to your email system – so there are fewer distractions and disruptions for your users.
Because Kaspersky Security for Linux Mail Server also achieves a very low rate of false positives, your email system benefits from rigorous protection – without the inconvenience and disruptions that result from large volumes of legitimate emails being incorrectly identified as spam and being quarantined.
Cloud-assisted anti-spam & anti-phishing… deliver better protection
Kaspersky Security for Linux Mail Server incorporates Enforced Anti-Spam Updates Service (EASUS) – to reduce your email system’s ‘window of exposure’ to newly launched spam attacks. Integration with the Kaspersky Security Network (KSN) ensures your email system receives real-time information about new spam – as soon as it’s available on Kaspersky’s cloud-based database.
In addition, Kaspersky’s cloud-based Reputation Filtering technology uses sophisticated content-analysis tools to identify possible spam – and it employs cloud-assisted capabilities to ‘compare notes with other users’. As a result, you benefit from a Linux mail server security solution that processes messages with minimal latency, while it further reduces the number of false positives and increases the overall detection rate.
Kaspersky’s latest anti-phishing module also receives real-time updates from the cloud-based Kaspersky Security Network. So you benefit from improved detection that can defend your corporate email system – and your users – against emails that contain links to phishing websites.
Effective anti-malware engine and exploits detection

You can integrate Kaspersky Security for Linux Mail Server’s reporting and monitoring facilities into your existing monitoring system (SNMP), or you can manage the application via Kaspersky Security Center – Kaspersky’s easy-to-use management console.
Integration eliminates hassle
Kaspersky Security for Linux Mail Server can be integrated with popular Linux-based Mail Transfer Agents (MTAs) – including Postfix, Sendmail, Exim and qmail.
