What technology helps to reduce how often messages are scanned in an organization?

Antivirus stamping is a technology that plays a crucial role in reducing the frequency of message scanning within an organization. When antivirus scanning is applied to an email, the scanning process analyzes the message and its attachments for potential threats. Once a message is scanned and deemed safe, subsequent scans of the same message can be avoided through the use of antivirus stamping. This means that the message will be marked as "safe," thereby preventing it from being scanned again every time it is accessed or forwarded. This process not only expedites email delivery but also diminishes the overall load on the email server, improving efficiency while still maintaining security.

In contrast, other options focus on different aspects of email management. Attachment filtering, for instance, is primarily concerned with blocking certain types of files and does not necessarily reduce the frequency of scanning for already scanned messages. Message queuing pertains to the organization and delivery of messages rather than their security processing, and load balancing is used to distribute workloads across multiple servers but does not specifically address the scanning process of messages.
