[Fix Your SPF Errors Now](/email/spf-record-check) _The presence of multiple SPF records is a prominent reason for SPF authentication errors_, besides syntax error and [SPF too many DNS lookups](/content/spf-too-many-dns-lookups). However, it is not an incorrigible error. Let’s discuss the ‘multiple records’ authentication error in detail and what to do about it. ![spf too many dns lookups](https://media.mailhop.org/duocircle/images/2020/12/edit-spf-record.png) ### What Defines Multiple SPF Records? _The multiple SPF records instance is when a domain has set up more than one SPF record_. It could be due to either overlooking the first record’s existence or assuming that an association with two or more email service providers requires creating an equal number of **SPF records**. It gives rise to a multiple SPF records error. ### ​Why Not To Have Multiple SPF Records? [Several errors](https://blog.mailtrap.io/multiple-spf-records/) trigger SPF failure, and multiple records happen to be the most common of them all. It is advisable to avoid having multiple SPF records because: - They lead to [permerror SPF permanent error too many DNS lookups](/content/spf-too-many-dns-lookups/permerror-spf-permanent-error-too-many-dns-lookups). - They cause email non-delivery and SPF authentication failure. - _[SPF lookup failure](/content/spf-too-many-dns-lookups/spf-lookup-failure) ultimately results in business loss_, spam emails, and **phishing attacks**. ![spf lookup](https://media.mailhop.org/duocircle/images/2020/12/spf-multiple-ip.png)![multiple spf records](https://media.mailhop.org/duocircle/images/2020/12/check-spf-record.png) ### How To Avoid Multiple SPF Records? Since it’s a _rule not to have more than one SPF record per domain_, all sources need to be edited and accommodated into a single SPF record. The following are some ways to accomplish it. - The error of multiple **SPF records** can be removed by merging the two (or more) SPF records and creating a single record inclusive of all sources. _One can have various sources in a single SPF record as long as the total length doesn’t exceed the 255-character limit_. - Another effective way to avoid exceeding the SPF 10-DNS- [SPF lookup](/content/spf-too-many-dns-lookups/spf-lookup) limit is to use [SPF flattening](https://www.autospf.com/#features) tools, which replace domains with their IP addresses, thus eliminating the need for an [SPF lookup counter](/content/spf-too-many-dns-lookups/spf-lookup-counter). - **SPF flattening** requires someone to manually update the IP address every time the server alters the IP address. _Many enterprises have incurred huge losses because of invalidated DNS records created when SPF flattening backfires_. However, this may be solved by using [SPF compression](/content/spf-too-many-dns-lookups/spf-compression) tools, which ensure scrupulous SPF record management. ### How To Merge Multiple SPF Records? _Multiple SPF records can be merged to create a single record_ by keeping the following rules in mind: - **The Use Of v=spf1 And all:** The rule is to use v=spf1 and all just once throughout the record. v=spf1 _must only appear in the beginning_, and all, in the end. Everything else regarding the domains comes in between the two. Example – Let’s say the following two records need to be merged to **validate your DNS** record: `v=spf1 ip4:2089:4990:4086::/47 ~all` `v=spf1 include:_spf.google.com ~all` The merged record should look something like this: `v=spf1 ip4:2089:4990:4086::/47 include:_spf.google.com ~all` - **10 DNS Limit:** While merging two or more SPF records, _remember to keep the 10-DNS [SPF lookup limit](/content/spf-too-many-dns-lookups/spf-lookup-limit) in mind_ and make minimal use of the ‘include’ mechanism. - **The Use Of SPF Validator Tool:** The last step is to validate the **merged SPF record** and check for errors. With this done, the recipient’s mailbox will identify and accept emails from all domains listed in the SPF record. _SPF records are crucial to enterprise email management_. Therefore errors caused by multiple SPF records or SPF too many DNS lookups need to be scrutinized and eliminated before they can cost financial or reputational loss to an organization. ![spf records](https://media.mailhop.org/duocircle/images/2020/12/spf-record-testing-tools.png) ##### Join the thousands of organizations that use DuoCircle --- Find out how affordable it is for your organization today and be pleasantly surprised.
