When troubleshooting mail delivery issues, you may see SPF errors similar to the following on the incoming mail server:

SPF PermError: too many DNS lookups

SPF Permanent Error: too many DNS lookups

SPF Fail: too many DNS lookups

This information indicates that the SPF record on your domain name contains more than 10 DNS queries, which makes the SPF record violate the SPF 10 query limit of the SPF specification.

When this error occurs, SPF returns a PermError (permanent error) that prevents SPF validation from passing. If the final message verification result fails, the message will most likely not reach the inbox.

Steps to fix a problem with SPF PermError: too many DNS lookups

Follow these 3 steps to fix the problem.

1. Jump to the Safe SPF function page of DMARCLY

Log in to the control panel of DMARCLY and go to DNS Records-> Safe SPF.

two。 Set Safe SPF on the domain name

Select the domain name of the SPF record that has been queried more than 10 times by DNS. You need to set Safe SPF on this domain name to break the 10 DNS query limit of SPF.

Click "Set Up Safe SPF". Enter the original SPF record on the domain name. Click "Generate Safe SPF Record".

Your original SPF record will be converted to a Safe SPF record. The Safe SPF record is a fully valid SPF record and contains the same IP address as the original SPF record, but performs fewer DNS queries.

Now publish the generated Safe SPF record to the domain name in DNS. Then click "Save Safe SPF".

3. Confirm that the SPF PermError has been repaired

Use the online SPF record Checker to check the domain name, and you will now see that the number of DNS queries is within the 10 DNS query limit. Please note that DNS propagation takes some time, so if you do not see a new SPF record, please try again in 5 minutes.

Now your original SPF record containing 10 DNS queries has become a Safe SPF record. This Safe SPF record contains the same IP address as the original and executes no more than 10 DNS queries. Moreover, when any third-party service changes, the Safe SPF record is automatically updated, so it is always synchronized with the original SPF record.

Now you don't have to worry about the annoying SPF PermError: too many DNS lookups problem anymore!
