Which Policy is NOT affected by an Auto-Allow entry?

An Auto-Allow entry is a feature used in email security systems to automatically permit specific senders or domains, ensuring that emails from these trusted sources are not blocked or filtered. The correct answer pertains to the capabilities and functions of each policy concerning Auto-Allow entries.

Content examination focuses on analyzing the contents of an email, which often includes filtering based on keywords, attachments, and other characteristics. This type of review is not influenced by Auto-Allow entries since the policy examines emails for potential threats regardless of sender trust. Therefore, even if an email is from an Auto-Allow source, its content still undergoes examination for compliance with security protocols.

On the other hand, spam scanning, greylisting, and RBL (Real-time Blackhole List) are directly impacted by Auto-Allow entries. These processes involve evaluating the reputation of the sender or applying heuristics based on sender behavior. If an Auto-Allow entry is present, emails from that sender would bypass these filters, which could lead to risks if those emails contain malicious content. Thus, it's essential to understand that content examination acts independently of sender reputation, making it the policy that is not affected by Auto-Allow entries.
