Email forwarding SMTP domains must be restricted.

An XCCDF Rule

Description

Auto-forwarded email accounts do not meet the requirement for digital signature and encryption of CUI and PII IAW DoDI 8520.2 (reference ee) and DoD Director for Administration and Management memorandum, 'Safeguarding Against and Responding to the Breach of Personally Identifiable Information.’ Use of forwarding set by an administrator interferes with non-repudiation requirements that each end user be responsible for creation and destination of email data.
