What are the Challenges in Using Authentication Protocols?
While these protocols are highly effective, they do come with challenges:
Complexity: Setting up and managing SPF, DKIM, and DMARC can be technically complex, especially for those unfamiliar with DNS settings. Maintenance: Regular updates and maintenance are required to ensure that all authorized IP addresses are correctly listed and that DKIM keys are rotated periodically. Interoperability: Ensuring that all email systems and third-party services are compatible with these protocols can be challenging.
