Graymail refers to solicited bulk email messages that do not fit the definition of spam email messages. Trend Micro Email Security detects marketing messages and newsletters, social network notifications, forum notifications, and bulk email messages as graymail messages.


  1. Select “Graymail”.
  2. Click Graymail.
    The Graymail Detection Setting screen appears.
  3. Select at least one graymail category from the following:
    • Marketing message and newsletter
    • Social network notification
    • Forum notification
    • Bulk email message
  4. To omit the IP addresses of specific mail servers from this rule, select Enable the graymail exception list under Graymail Exception List.
  5. Specify IP addresses that you want to bypass graymail scanning.
    The rule will not apply to graymail messages from IP addresses in this exception list. The list is specific just to the rule being edited.
  6. Click Save.
