What is the name of the Group that corresponds with the global Block Sender policy?

The name of the Group that corresponds with the global Block Sender policy is Blocked Senders. This policy is essential for email security as it allows organizations to specify certain email addresses or domains that should be blocked from sending emails to their users. By utilizing the Blocked Senders group, administrators effectively create a list of unreliable or malicious sources, which enhances the overall security of their email communications.

When emails from individuals or organizations listed in the Blocked Senders group attempt to reach users within the organization, these emails are automatically rejected or filtered out, preventing potential spam, phishing attempts, or other malicious activities. This proactive approach helps protect the organization from threats that may originate from known bad actors.

Other groups, such as Allowed Senders and Trusted Senders, serve different purposes focused on permitting rather than blocking, and Restricted Senders may not align directly with the global Block Sender policy. The focus of the Blocked Senders group is clear: it's about denying entry to specified senders, thereby fortifying email security measures.
