Why SPF Flattening Solves DNS Lookup Limits
SPF records are limited to 10 DNS lookups. Flattening converts includes into IP addresses, preventing authentication failures while maintaining security and deliverability.
Optimize SPF records by converting DNS lookups into IP addresses to stay within the 10-lookup limit and prevent authentication failures.
