Overview
Mimecast is pleased to announce upcoming improvements to Mimecast Email Incident Response (MEIR) with changes to end-user feedback.
What's changing
End-User Feedback
End-user feedback in response to a reported message informs the user of the outcome. At the same time, it incentivizes further reports of messages by that user. Mimecast is now extending this feature to support sending notifications to end-users for all classifications. Granular control is available to configure which classifications trigger a feedback email to the end user. For more details on configuring this, see Mimecast Email Incident Response - End User Feedback.
The newly available options for categorizing and receiving feedback for reported emails are as follows:
| Field / Option | Description |
| Benign |
If selected, end users will receive a feedback email in response
to classifying a message as Benign. Note: This excludes Mimecast Awareness Training and 3rd Party Awareness Training simulations. |
| Indeterminate | If selected, end users will receive a feedback email in response to classifying a message as Indeterminate. |
| Malicious | If selected, end users will receive a feedback email in response to classifying a message as Malicious. |
| Simulated | If selected, end users will receive a feedback email in response to classifying a message as Mimecast Awareness Training or 3rd Party Awareness Training. |
Managed Senders Block List
The sender gets added to the personally managed senders block list when reporting a message. This is correct in most cases where messages are spam or malicious. Additionally, for MEIR customers, the sender will only be added to a block list if it’s spam or malicious as a part of the MEIR analysis & classification process.
For legitimate messages, this can create management overhead and/or missing critical (legitimate) messages. Moving forward, messages classified as “Benign - legitimate” will not be added to the managed senders block list.
Recommended actions
- No user interaction is required. Your MEIR service will continue operating normally. If you wish to configure these additional options, follow the configuration steps in the article Mimecast Email Incident Response - End User Feedback.
For new subscribers to the MEIR service, the default behavior will be set to responding to all four reported message classifications.
