Trend Micro Email Security allows you to configure the following to filter senders of incoming messages for the entire organization, a managed domain, or a specific recipient address in your managed domains:
  • Approved senders
    Specifies the senders to allow using specific email addresses or entire domains.
  • Blocked senders
    Specifies the senders to block using specific email addresses or entire domains.
  • Sender filter settings
    • Specifies the type of sender addresses collected to match the approved and blocked sender lists.
    • Specifies whether to insert an X-Header in the message header for email messages matching approved senders.
Trend Micro Email Security achieves a two-way synchronization between the following data:
  • Senders configured for a specific end user on the administrator console
  • Senders added by that user through the End User Console or quarantine digest notifications
Any changes made to the approved or blocked senders of an end user either on the administrator console or End User Console should be reflected to the other location.
