Server Wide or User Managed

System administrators can elect to lock down the server as a whole, and implement their own robust antispam policies, or allow domain administrators to manage antispam options. And if they want, domain administrators can even let their users manage what they want done to low, medium and high probability messages.

Additional Email Server Antispam

Antispam from Cyren by Data443

Increase your antispam protection using RPD technology and IP Reputation from Cyren by Data443:

  • Cyren Premium Antispam - using their Recurrent Pattern Detection (RPD) it's possible to dramatically increase the efficiency of spam protection while offloading the CPU cycles to Cyren's servers.
  • Cyren IP Reputation - Cyren's global system identifies and tracks IP addresses and ranks them according their potential for malicious behavior. IP Reputation is included with the Cyren Premium Antispam add-on, so there's no additional licensing.
  • Offers protection against phishing and malware, attachment analysis, advanced threat intelligence, real time blocking, and more for both inbound and outbound messages. See Cyren by Data443's competitive analysis PDF.

Message Sniffer from Arm Research Labs

Message Sniffer uses advanced pattern detection and collaborative learning technologies to accurately identify spam, scams, viruses, and other email borne malware before it hits inboxes.

Consistent Rulesets

For system administrators who manage multiple mail servers, it's possible to configure antispam options on one server, then export those rules and import them into another SmarterMail server on the network. This allows for a robust, consistent set of antispam options on every mail server.

Antispam Management

Using SmarterMail's web interface, system administrators can access all security features using their favorite web browser. In addition, all antispam settings are contained in a single JSON file, so system admins can easily transfer antispam settings so that all SmarterMail servers are consistently managed and consistently secured.

Enterprise Level Antivirus

SmarterMail includes effective and self-updating virus protection measures to ensure you run a secure server via ClamAV, which is included with every SmarterMail installation. SmarterMail also employs Microsoft Defender Antivirus, for added protection. Administrators can also integrate SmarterMail with third-party antivirus programs via a command-line execution. This can be an efficient solution for high-volume mail environments by reducing the burden on the mail server itself.

Antivirus from Cyren by Data443

Cyren Zero-hour Outbreak Detection is a complementary service to help identify "zero hour", or recently released, viruses and malware. It does this by identifying unusual behaviors or anomalies in data flows that could indicate a malware attack. It monitors and analyzes the volume and frequency of attachments sent through mail traffic, identifying potential outbreaks based on the sheer scale and speed of distribution, which is typical of many worm or mass-mailing virus and malware attacks.

Administrators can also use any other antivirus protection, either installed on the server, in the cloud or even via command line.

Additional Security

While keeping an email server protected from viruses and other malware is a great start, there's more to having a secure mail server than just antivirus protection. SmarterMail includes additional security features, including:

  • Password policy enforcement
  • Two-Step Authentication (app passwords + authenticator)
  • Built-in Intrusion Detection System (IDS)
  • Access restrictions by IP address
  • Email harvest attack detection
  • Denial of Service (DoS) attack prevention
  • Brute force detection
  • A powerful Event system to create actions based on any of the above, and more
