Where is the Auto Allow entry created when sending an email to an external recipient?

When sending an email to an external recipient, the Auto Allow entry is created in the X-Permitted Senders Group. This group is specifically designed to enhance email deliverability by tracking domains that have been permitted to send emails on behalf of the organization. By placing the entry in the X-Permitted Senders Group, the system can recognize that the sender is allowed to communicate with external addresses without being blocked or placed in a quarantine status.

The functionality of the X-Permitted Senders Group helps streamline the email process, particularly when dealing with external communication, ensuring that legitimate emails proceed smoothly without unnecessary interruptions. This is crucial for maintaining effective communication and safeguarding the organization from potential phishing attacks by ensuring only trusted sources are whitelisted.

In contrast, the other groups mentioned serve different purposes. The Blocked Senders Group is used to manage and block known spam or malicious senders, while the Whitelist Group generally consists of trusted domains or email addresses that bypass certain filtering rules, but it is not specifically for auto-allowing entries based on outbound communications. Managed Senders refers to a broader category of sending policies rather than the specific mechanism for automatically allowing emails to external recipients.
