Key Features

The following table provides a list of features that are available in the ESET Mail Security.

True 64-bit product core

Adding higher performance and stability to the product core components.


This essential component went through a major redesign and is now using brand new award winning engine with improved performance. Validation of messages using SPF and DKIM and Mail server SMTP protection.

Anti-Phishing protection

A feature which prevents users from accessing web pages known for phishing. Email messages may contain links which lead to phishing web pages and ESET Mail Security uses sophisticated parser that searches message body and subject of incoming email messages to identify such links (URL's). The links are compared against phishing database.


The rules menu item allows administrators to manually define email filtering conditions and actions to take with filtered emails. Rules in the latest version of ESET Mail Security were redesigned to allow for greater flexibility giving the user even more possibilities.

Mail quarantine manager

Administrator can inspect objects in this storage section and decide to delete or release them. This feature offers simple management of emails quarantined by the transport agent.

On-demand database scan

On-demand database scanner is now using parallel scanning to improve the performance.

Mail Quarantine

One of the basic steps in setting up protection in ESET Mail Security is creating the quarantine that safely stores infected notes. Only the administrator of the IBM Domino mail server has access to the quarantine. This quarantine is excluded from additional scanning.

ESET Cluster

Similar to ESET File Security 6 for Microsoft Windows Server, joining workstations to nodes will offer additional automation of management due to the ability to distribute one configuration policy across all cluster members. The creation of clusters themselves is possible using the node installed, which can then install and initiates all nodes remotely. ESET server products are able to communicate with each other and exchange data such as configuration and notifications, and can Synchronize greylisting databases as well as synchronize data necessary for proper operation of a group of product instances. This allows for the same configuration of the product for all members of a cluster. Windows Failover Clusters and Network Load Balancing (NLB) Clusters are supported by ESET Mail Security. Additionally, you can add ESET Cluster members manually without the need for a specific Windows Cluster. ESET Clusters work in both domain and workgroup environments.

Component-based installation

Choose which components you want to add or remove.

Storage scan

Scans all shared files on a local server. This makes it easy to selectively scan only user data that is stored on the file server.

Processes exclusions

Excludes specific processes from Antivirus on-access scanning. Due to the critical role of dedicated servers (application server, storage server, etc.) regular backups are mandatory to guarantee timely recovery from fatal incidents of any kind. To improve backup speed, process integrity and service availability, some techniques that are known to conflict with file-level antivirus protection are used during backup. Similar problems can occur when attempting live migrations of virtual machines. The only effective way to avoid both situations is to deactivate antivirus software. By excluding specific process (for example those of the backup solution) all file operations attributed to such excluded process are ignored and considered safe, thus minimizing interference with the backup process. We recommend that you use caution when creating exclusions – a backup tool that has been excluded can access infected files without triggering  an alert which is why extended permissions are only allowed in the real-time protection module.

eShell (ESET Shell)

eShell 2.0 is now available in ESET Mail Security. eShell is a command line interface that offers advanced users and administrators more comprehensive options to manage ESET server products.


Better integration with ESET PROTECT including the ability to schedule On-demand scan. For more information about ESET PROTECT, see ESET PROTECT Online help exlink.

Hyper-V scan

Is a new technology that allows for scanning of Virtual Machine (VM) disks on Microsoft Hyper-V Server exlink without the need of any "Agent" on the particular VM.
