SPF Flattening

One click the Unlimited Lookup Auto SPF Record, which never fails to meet 10 DNS Lookups! An automatic SPF flattening approach that immediately mitigates SPF PermError and helps you to keep under SPF ten search limits.E-mail authentication method SPF (sender policy framework) is used to prevent the spoofing of e-mail by e-mail services. The problem is that SPF registers flexibly, since it needs up to 10 DNS searches. You probably didn't know but a single service can use several DNS searches and you can easily exceed the limit by combining services.

"SPF flattening" is one solution to the SPF search boundary. Flattening simply substitutes all domains in the SPF record for their IP addresses, eliminating the need for DNS search. The problem is that email service providers can modify or add to their IP address without telling you about this "manual" flattening. Your SPF record is inaccurate, leading to the same problem with e-mail delivery.
