ESET Mail Security Antispam incorporates multiple technologies (RBL and DNSBL, Fingerprinting, Reputation checking, Content analysis, Rules, manual whitelisting/blacklisting, Backscatter protection and message validation using SPF and DKIM) to maximize detection. ESET Mail Security Antispam is cloud based and most of the cloud databases are located in ESET data centers. Antispam cloud services allow for prompt data updates which provides quicker reaction time in case of an emergence of new spam.

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.

Rules

The rules enables administrators to filter unwanted emails and attachments based on company's policy. Attachments such as executables, multimedia files, password protected archives, etc. Different actions can be performed with filtered email messages and their attachments, for example quarantine, delete, send notification or log to events.

Export to syslog server (Arcsight)

Allows for the contents of Mail server protection log to be duplicated to syslog server in Common Event Format (CEF) for use with log management solutions such as Micro Focus ArcSight.  Events can be fed via SmartConnector to ArcSight, or exported to files. This provides for a convenient way of centralized monitoring and management of security events. You can benefit from this feature especially if you have a complex infrastructure with a large number of Microsoft Exchange Servers with ESET Mail Security solution.

Office 365 mailbox scan

For businesses who use hybrid Exchange environment, adds the capability to scan mailboxes in the cloud.

ESET LiveGuard Advanced

ESET Cloud-based service. When ESET Mail Security evaluates an email message as suspicious, it is temporarily put it into the ESET LiveGuard Advanced quarantine. A suspicious email message is automatically submitted to ESET LiveGuard Advanced server for analysis by advanced malware detection engines. ESET Mail Security then receives a result of the analysis and suspicious email message is dealt with depending on the result.

Mail quarantine manager with web interface

Administrator can inspect quarantined objects and decide to delete or release them. This feature offers easy to use management tool.

Quarantine web interface allows remote management of the content. It is possible to choose its administrators and/or delegate access. Additionally, users can view and manage their own spam after logging to the Mail Quarantine Web interface, having access to their messages only.

Mail quarantine reports

Quarantine reports are emails sent to selected users or administrators to provide information about all quarantined email messages. It also enables them to remotely manage quarantined content.

On-demand mailbox database scan

On-demand mailbox database scan gives administrators an option to scan selected mailboxes manually, or schedule the scan out of business hours. Mailbox database scanner uses the EWS (Exchange Web Services) API to connect to Microsoft Exchange Server via HTTP/HTTPS. Also, the scanner uses parallelism during scan process to improve the performance.

ESET Cluster

ESET Cluster allows for management of multiple servers from a single location. Similar to ESET File Security for Microsoft Windows Server, joining server nodes to a cluster makes management easier due to the ability to distribute one configuration across all cluster member nodes. ESET Cluster can also be used to synchronize greylisting databases and contents of the Local mail quarantine.

Processes exclusions

Excludes specific processes from Anti-Malware on-access scanning. Anti-Malware on-access scanning may cause conflicts in certain situations, for example during a backup process or live migrations of virtual machines. Processes exclusions help minimize the risk of such potential conflicts and improve the performance of excluded applications, which in turn has a positive effect on the overall performance and stability of the whole system. The exclusion of a process / application is an exclusion of its executable file (.exe).
