Explanation

Creating a DKIM signing profile on the Cisco Secure Email Gateway defines the key and domain to use, but it does not automatically apply to outbound mail. To activate DKIM signing, you must enable it within the Mail Flow Policy that governs outbound connections. The Mail Flow Policy is where the SEG enforces sending behaviors including DKIM signing. Destination Controls (Option A) manage delivery settings, not signing. A signing profile alone (Option C) is insufficient without associating it with a mail flow policy. Outbound content filters (Option D) can reference DKIM actions but are not the standard mechanism for enabling DKIM signing globally.
