You can manage your own list of addresses and domains in Mimecast for Outlook that are blocked, permitted, and automatically allowed. This is all achieved from your Managed Senders view. This view provides functionality to:

  • Filter entries
  • Add entries
  • Delete entries

Managed Senders

To open the Managed Senders view:

  1. Open Mimecast for Outlook.
  2. Click on the Mimecast ribbon.
  3. Click on the Managed Senders icon in the Email Gateway section.

There are three distinct lists of addresses and domains in the Managed Senders view. Each list can be managed separately:

Managed Senders ListDescription
Auto PermittedThe sender addresses and domains that are automatically added to your permitted list, by virtue that they are specified in an Auto Allow policy.
BlockedThe sender addresses and domains that have been manually added to your blocked list (e.g. they've been flagged as spam).
PermittedThe sender addresses and domains that have been manually added to your permitted list.

 

With the Managed Senders view open, you can perform the actions listed below. See the relevant section for your Mimecast for Outlook version for further details.

 

Filtering the Managed Senders View

    • Addresses Only - signified by the Address Icon icon.
    • Domains Only - signified by the Domain Icon icon.
