What adjustments should be made to the Safe Attachments policies to speed up email delivery with attachments while maintaining scanning?

Dynamic Delivery is the correct choice because it allows attachments to be delivered to the recipient with an immediate placeholder, enabling them to access the email content right away while still applying scanning to the actual attachments in real-time. This is particularly beneficial in environments where timely email delivery is crucial, as it reduces the waiting time for users while ensuring that malicious attachments are assessed for threats.

By using Dynamic Delivery, the system sends the email through but holds back the potentially hazardous attachment for scanning. Once it’s confirmed safe, the actual attachment is added to the email. This method strikes a balance by maintaining security without significantly delaying the delivery process.

Other options, while they may involve some level of safety or delivery efficiency, do not effectively combine the immediate availability of the email content with subsequent threat scanning in the same way Dynamic Delivery does.
