Jumping the lookup hurdle to push the project over the finish line
SPF lookups are a common hurdle for IT teams as a DNS’ lookup limit is capped at 10. This is to reduce the potential for highly amplified Denial of Service (DoS) attacks against the Internet’s DNS infrastructure. For every email service there are one or more lookups added to the list. A popular service like Gmail, for example, has 3 lookups alone! After an email marketing platform was added to the organization’s services, the CTO found, “we couldn’t handle the number of SPF entries on our stock integration for all of our email sources”, confirming the need for a solution.
It quickly became apparent to the CTO that “we had no guidance on what to do from the weekly digests our previous DMARC reporting tool gave us. It was only when searching for a solution that we discovered Dynamic SPF. This tool and OnDMARC’s ongoing guidance got us over our technical IP limitations and enabled us to move forward with the project by managing all lookups from inside our account”. However, when using OnDMARC, the team were able to get to work quickly and simplified the management of their 20+ entries within the first 3 days of setting up their account.
