KoruMail Reputation Network (KRN)


  • KoruMail Reputation Network is an IP reputation scoring system developed by Comodo.
  • It not only includes traditional features such as real-time IP blacklists (RBL) but also has ‘whitelist’ and ‘greylisting ignore’ features.
  • The whitelisting feature means emails that come from trusted sources will be permitted, which helps to reduce false-positive rates.

    The interface allows administrators to:

    • Enable / disable a KRN server
    • Configure KRN settings
