Security & Best Practices

DKIM key management, rotation, and security guidance.

DKIM keys should be rotated periodically to limit exposure if a private key is compromised. Longer keys (2048-bit) provide stronger security but require DNS providers that support long TXT records. These guides cover key rotation procedures, security auditing for DKIM, and how DKIM fits into a broader email security strategy alongside SPF and DMARC.
