Answers to your Frequently Asked Questions on Sender Policy Framework
AutoSPF offers an automatic SPF flattening service that fixes the ‘too many DNS lookup’ error in your SPF record. It works by replacing all the domains in your SPF record with their IP addresses to eliminate the need for frequent DNS lookups.
The term “flattening an SPF record” typically refers to simplifying or condensing a Sender Policy Framework (SPF) record by removing unnecessary or redundant entries. It involves an evaluation and consolidation of ‘include’ statements and minimization of nested lookups to stay within the maximum lookup limit of 10.
AutoSPF simplifies and condenses SPF TXT records that minimizes the risk of SPF failures, enhances readability, and contributes to a more reliable email authentication process. This reduces the instances of false positives and improves the chances of legitimate emails being successfully delivered to desired recipients’ inboxes.
Manual SPF record flattening is discouraged as it involves the risk of errors, impacts readability, and leads to unintended misconfigurations. On the other hand, automated tools are more reliable as they ensure accuracy, adherence to best practices, and minimize the chances of problems that could impact email deliverability and security.
Yes, you must update a flattened SPF record whenever there are modifications in your email infrastructure and sending practices. Ensure your SPF record accurately reflects the IP addresses and mail servers authorized to send emails on behalf of your organization.
No, correctly flattened SPF records don’t compromise security. However, inaccuracies or omissions during the process can introduce risks. Hence, automated tools are suggested for accuracy and adherence to best practices, which minimizes the potential for misconfigurations that could expose your domains to phishing.
Risks can emerge from misconfigurations, oversights, and complexities, especially if flattened manually. This can potentially compromise email security and authentication. That’s why automated tools are recommended to nullify these risks and ensure accurate SPF record management.
SPF flattening doesn’t impact DKIM and DMARC if done correctly. However, since SPF, DKIM, and DMARC work in accordance with each other, it’s important to configure and update all three records accurately for effective email authentication.
The “Too many DNS lookups” error occurs in the context of SPF records when the number of DNS queries required to authenticate an email exceeds the specified limit of 10.
