When an address triggers the Permitted Senders entry, which three Policies does it bypass?

The selected answer is accurate because when an address triggers the Permitted Senders entry, it is essentially marked as trustworthy within the email security framework. This designation allows emails from that sender to bypass several security policies typically applied to incoming messages.

Specifically, the three policies that are bypassed include content examination, spam scanning, and greylisting.

• Content examination is the process of reviewing the email's content for any malicious or harmful elements. By bypassing this policy for permitted senders, it allows their emails to be delivered swiftly without undergoing these scanning procedures.

• Spam scanning is another critical policy that detects unsolicited or harmful emails. By avoiding spam scanning for senders deemed as permitted, organizations can ensure that legitimate communications are not delayed or misclassified as spam.

• Greylisting is a technique used to temporarily reject emails from unrecognized senders to prevent spam, allowing only legitimate senders to successfully retransmit emails after a short delay. Permitted senders are exempt from this process, ensuring quicker delivery.

Thus, recognizing an address as a Permitted Sender effectively streamlines the email delivery process from that sender by bypassing these security measures, which are typically used to filter out potential threats.
