[ Talk to an Expert → ](/contact/) [ See what we make ](/products/) ## What Happens When Permerror SPF Permanent Error Too Many DNS Lookups Occurs? For the recipient servers’ convenience and the **prevention of DDoS attacks**, _SPF records must be limited to ten mechanisms_. It is also known as the SPF lookup limit. Failing to maintain the limit would result in a permerror [SPF too many DNS lookups](/content/spf-too-many-dns-lookups). [Fix Your SPF Errors Now](/email/spf-record-check) ![multiple spf records](https://media.mailhop.org/duocircle/images/2020/12/how-to-test-spf.png) ### How To Deal With SPF Lookup Failure? The following measures may be adopted to check the [SPF lookup counter](/content/spf-too-many-dns-lookups/spf-lookup-counter) and avoid exceeding the [SPF lookup](/content/spf-too-many-dns-lookups/spf-lookup) limit: - Modifiers: **Avoid extra modifiers** like ‘include,’ ‘a’, ‘mx,’ ‘ptr,’ ‘exists,’ ‘redirect,’ etc., as they count against the SPF lookup limit. - SPF Flattening: [SPF lookup errors](https://www.autospf.com/) may be reduced by [SPF flattening](/content/spf-too-many-dns-lookups/spf-flattening), which is a _manual way of replacing domain names with their IP addresses to eliminate the need for separate DNS records_. However, this manual solution needs constant monitoring as a change of IP address by an email service provider would mean **SPF record errors** for domain owners. - [Multiple SPF Records](/content/spf-too-many-dns-lookups/multiple-spf-records): Yet another error causing SPF lookup failure is that of more than one SPF records, which can be avoided by merging the two (or more) SPF records of a domain into a single one. - SPF Compression: The [SPF compression](/content/spf-too-many-dns-lookups/spf-compression) tool goes a step ahead and ensures that the [SPF lookup limit](/content/spf-too-many-dns-lookups/spf-lookup-limit) is maintained by repairing records and authorizing email service providers. Thus, the above steps are capable of preventing the **permerror SPF** permanent error too many DNS lookups. _SPF records are an effective way to ensure email deliverability_, spam control, and the prevention of DDoS or other forms of cyberattacks. However, [SPF record errors](https://www.xspdf.com/resolution/52341983.html) such as the “permerror SPF permanent error too many DNS lookups” and other similar ones hinder this secure and fast email delivery process. The ways mentioned above help _reduce the chances of [SPF lookup failure](/content/spf-too-many-dns-lookups/spf-lookup-failure)_. ## Ready to talk? Same-day response from someone technical.
