The Exchange Post Office Protocol 3 (POP3) service must be disabled.
An XCCDF Rule
Description
POP3 is not approved for use within the DoD. It uses a clear-text-based user name and password and does not support the DoD standard for PKI for email access. User name and password could easily be captured from the network, allowing a malicious user to access other system features. Uninstalling or disabling the service will prevent the use of POP3.
