Active content is classified as Safe, Suspect, Indeterminate or Encrypted and for each category different actions can be chosen (deliver, clean and deliver, block)
  • Dictionary Based Rules; you can create/import dictionaries of words and phrases, you can define how many occurences trigger an action, you can configure the action (block, forward, add header) based on dictionary, sender, recipient

  • Theme Customization Tool: Esva web interface colors can now be customized with a simple pickup color table

    Protection against brute force login attempts through the web interface, through smtp-auth and through ssh
  • LDAP import: new users inherit the settings of the domain admin user
  • Attachment Filters now support regular expressions on file names
  • Added an option to block the entire message when a non-allowed file is attached (instead of just removing the file)
  • Distributed setup: the configuration is now automatically versioned and nodes with outdated configuration are highlighted
