Analyze DNS Delegation
Check how your DKIM record is structured at the DNS layer. Identify CNAME delegations (commonly used by Mailchimp, SendGrid) and analyze string splitting for large RSA keys.
DKIM Tools
Audit your DKIM authentication strictly at the DNS layer. Trace complex CNAME delegations, verify 2048-bit string splitting, and diagnose NXDOMAIN routing errors to ensure flawless DMARC compliance.

DKIM authentication depends heavily on your DNS configuration. A perfectly encrypted key will fail if your DNS provider truncates the string, misconfigures a CNAME, or hits UDP limits.
