What is the result of a Blocked Sender Policy being applied?

When a Blocked Sender Policy is applied, the primary outcome is that the email from the sender identified as blocked is not delivered to the recipient's inbox. This policy effectively prevents any emails from specified sources from reaching the recipient at all, thereby maintaining a cleaner and safer email environment. Implementing such a policy is crucial for organizations aiming to minimize unwanted communications, spam, and potential phishing attempts.

Other options imply different handling of the email, such as delivery, flagging, or redirection to spam folders, which do not align with the strict nature of a Blocked Sender Policy. The focus is on outright prevention of delivery, ensuring that any attempted communication from blocked senders is halted at the server level before it reaches the user's mailbox.
