About Accepted Traffic

If you select Accepted traffic as your search condition, a summary of email message traffic accepted by Trend Micro Email Security is displayed. Once a message is accepted, it goes through various stages of processing by Trend Micro Email Security.

This result summary is organized with recipient in mind, since mail tracking is mostly initiated by an end user. For a message that has multiple recipients, the result will be organized as one recipient per entry.

The following information is displayed for the Accepted traffic type:

  • Timestamp: The time the message was accepted by Trend Micro Email Security. Click on the Timestamp value to open the Mail Tracking Details window for a given message.
