Auto Allow Creation policies allow you to create exceptions to Auto Allow Policies that add external email addresses to a trusted database. Auto Allow policies ensure that inbound messages from a trusted external recipient are not subjected to spam checks. An Auto Allow Creation policy provides a way to exclude certain routes of traffic from this process.
Consider the following before creating a policy:
- An auto allow entry is automatically deleted if no emails are sent to the address for 120 days.
- By default email addresses are not added to the trusted database if:
- Auto-responses are sent (e.g. Out of Office messages).
- Suspected spam related emails are released and the recipient subsequently replies to the sender.
- Only messages that have been actively created by end users will have Auto Allow entries created. However there may be addresses that you want to exclude from this process when emails are sent outbound.
- When configuring Auto Allow Creation policies, don't apply them to mailshots or similar bulk email. This creates thousands of entries in your Managed Senders list, which accumulate over time and can cause performance issues when accessing the list.
Example Use Case
You 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 "Do not generate AAL entries" option:
Internal Address Exclusions
|From internal email address:||firstname.lastname@example.org|
|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|
