The Auto Allow Creation Policy lets Administrators create exceptions to the Auto Allow policy. The Auto Allow policy adds the external recipients of outbound emails to a Trusted Senders Database, and is created by default during the Mimecast Implementation process. The result is that inbound emails from the trusted external recipient, are not subjected to content and reputation spam checks. The Auto Allow Creation Policy provides a way to exclude certain routes of traffic from this process.

Benefits

Mimecast, by default, will not add any email addresses generated by auto responders to the trusted database. However there may be other traffic flows that you would like to exclude from the Auto Allow process. Also, an Auto Allow entry will not be created when a user replies to an email that was placed on Hold and subsequently released to them.

 

For example, if an Administrator implemented the Auto Allow Creation Policy to not generate AAL entries for any email sent to domain.com, an email sent by an end user to this domain would NOT result in the external recipient’s address being added to the Auto Allow trusted database. Therefore when an email is sent from domain.com inbound to internal users, their message will not bypass spam checks automatically.

 

Only emails that have been actively created by end users will have Auto Allow entries created. All auto responses (including out of office messages) do not generate Auto Allow entries. However there may be other addresses in your environment that you want to exclude from this process when emails are sent outbound.

Example Use Case

Some organizations may have a requirement to exclude certain internal or external addresses from generating Auto Allow entries. To enable this feature, create an Auto Allow Creation Policy with the policy option Do not generate AAL entries, as shown below:

 

Internal Address Exclusions

From internal email address:

sales@internaldomain.com

To:

Everyone

Apply Policy:

Do not generate AAL entries

External Address Exclusions

From internal email address:

Everyone

To Email Domain:

hotmail.com

Apply Policy:

Do not generate AAL entries

  • An Administrator Console logon with access to the ServicesGateway | Policies menu item.
