Dr.Web for Kerio Mail Servers

Anti-virus scan of messages and their attachments sent via SMTP and POP3

The anti-virus connects to the Kerio Mail Server and scans attached files and incoming and outgoing messages.


  • Perfect compatibility with Kerio mail servers tested by Kerio Technologies
  • Minimal message delivery time achieved through multi-thread scanning
  • Low system requirements and minimal use of local traffic
  • Flexible, user-friendly configuration system: customizable list of scanned objects and actions performed with detected viruses or suspicious files
  • Customizable actions for files that can't be scanned
  • Maintenance and configuration from Kerio mail server administration console

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.
