What Does ‘Too Many DNS Lookups’ Mean?
Your Sender Policy Framework (SPF) authenticates outgoing mail to prevent fraud. It does this by performing Domain Name System (DNS) lookups. The problem is that every system can only perform a maximum of 10 DNS lookups. Every email-sending service you use adds to that number – once it goes past 10, email deliveries start failing.
How Many Services Send Email on Your Behalf?
If you use a productivity app like Salesforce, it will use up eight of your ten DNS lookup slots. Every single third-party service that has email access adds at least one slot. It’s easy to exceed the ten-lookup limit just using a few third-party services.
What Happens When You Go Over the SPF Limit?
Most email providers don’t provide any warning when users exceed the DNS lookup limit. Emails simply fail to get delivered due to SPF Permerror. Domain authentication stops working. Hackers may be able to gain access to your domain. The lack of error handling means all this can happen right under your nose.
SPF Flattening and Monitoring: How It Works
The solution to getting around the DNS lookup limit is called “SPF flattening.” It involves manually inputting IP addresses into the SPF record, bypassing the need to refer to a DNS lookup table. This process must be monitored and repeated regularly, as third-party service providers can change their addresses whenever they want.
